2 About the HRP UWB option

2.1 Required options

About the HRP UWB option
HRP UWB signal properties
The equipment layout for generating HRP UWB signals includes:
Wideband baseband generator (R&S SMW-B9)
Wideband baseband main module (R&S SMW-B13XT)
Option HRP UWB (R&S SMW-K149) per signal path
Optional, option baseband extension to 1 GHz RF bandwidth extension (R&S SMW-K525) per signal path
Optional, option baseband extension to 2 GHz RF bandwidth extension (R&S SMW-K527) per signal path
You can generate signals via play-back of waveform files at the signal generator. To create the waveform file using R&S WinIQSIM2, you do not need a specific option.
To play back the waveform file at the signal generator, you have two options:
Install the R&S WinIQSIM2 option of the digital standard, e.g. R&S SMW-K255 for playing LTE waveforms
If supported, install the real-time option of the digital standard, e.g. R&S SMW-K55 for playing LTE waveforms
For more information, see data sheet.

2.2 HRP UWB signal properties

HRP UWB PHY signals employ short, band-limited pulses sent at high rate pulse repe­tition frequencies (HRP).

2.2.1 Frame structure

An HRP UWB PHY frame consists of a preamble part that contains the synchronization header (SHR) and a data part that contains a PHY header (PHR) and a PHY payload. The SHR in the preamble comprises the synchronization (SYNC) field and a start-of­frame delimiter (SFD) field.

Data
HRP-ERDEV
P802.15.4z/D07 introduced optional modes and a ciphered scramble time stamp (STS) sequence into the PHY to improve timestamp robustness and security and to increase the accuracy of ranging measurements.
A device incorporating these modes is referred to as a higher rate pulse repetition fre­quency UWB PHY based enhanced ranging capable device (HRP-ERDEV) and defined in P802.15.4z/D07, chapter 16.1, "General". Operation at the nominal 64 MHz pulse repetition frequency (PRF) is referred to as the base pulse repetition frequency (BPRF) mode. Operation at a higher PRF than the BPRF mode, is referred to as the higher pulse repetition frequency (HPRF) mode.
The frame structure of HRP-ERDEV is shown in the following figure, with the STS in different positions. The arrow shows the RMARKER reference position for each config­uration, which is the peak pulse location associated with the first chip following the SFD.

Figure 2-2: HRP-ERDEV frame structures with RMARKER position
2.2.1.1 Preamble
The SYNC and SFD fields in the preamble consist of repetitions of a preamble symbol Si. A preamble symbol is constructed from a ternary code sequence Ci = {–1,0,1} by
inserting several chip durations between code symbols. The supported code sequence lengths are 31 and 127 as defined in IEEE Std 802.15.4-2015 chapter 16.2.4, "Pream­ble timing parameters". In addition, code sequence length 91 is supported as defined in P802.15.4z/D07, chapter 16.2.5, "SYNC field". The number of inserted chip durations is also called delta length and depends on the length of the code sequence and chan­nel number.

The SYNC field portion of the SHR contains simple repetitions of the preamble symbol. The number of preamble symbol repetitions are 16, 64, 1024 and 4096 as defined in IEEE Std 802.15.4-2015, chapter 16.2.4, "Preamble timing parameters". In HPRF mode, the HRP-ERDEV supports 32 and 64 preamble symbol repetitions as defined in P802.15.4z/D07, chapter 16.2.5.1, "SYNC Field".
SFD field
The SFD field is spread by the preamble symbols. Each of the preamble symbols is multiplied by a sequence of {-1, 0, 1}. The supported SFD lengths are 8 (short) and 64 (long) as defined in IEEE Std 802.15.4-2015, chapter 16.2.5.2, "SFD field". In addition, the SFD sequences corresponding to the BPRF and HPRF modes are supported as defined in P802.15.4z/D07, chapter 16.2.5.2, "SFD Field".

2.2.1.2 Data
The PHR and PHY payload symbols are modulated using a combination of burst posi­tion modulation (BPM) and binary phase-shift keying (BPSK). Each symbol is com­posed of an active burst of UWB pulses and can carry two bits of information. One bit is used to determine the position of a burst of pulses, while an additional bit is used to modulate the phase (polarity) of this same burst. The various data rates are supported by using variable-length bursts.
PHR field
The PHR field conveys the information necessary to decode the packet to the receiver, including the following:
The PHR is modulated using BPM-BPSK at either 850 kb/s or 110 kb/s. For the BPRF mode, the PHR is modulated using BPM-BPSK at 850 kb/s (or optionally at 6.8 Mb/s).

2.3 Operating frequency bands

About the HRP UWB option
Operating frequency bands
PHY payload field
The PHY payload field is sent at the data rate indicated in the PHR. Due to the variable code sequence lengths and the different corresponding pulse repetition frequencies (PRFs) in the preamble, there are several admissible data rates the UWB PHY can support. The supported data rates are defined in IEEE Std 802.15.4-2015, chapter
16.2.6, "PHR field" and P802.15.4z/D07, chapter 16.2.6.2 "PHR field for HRP-ERDEV in BPRF mode".
The carrier center frequencies for UWB signals are defined in IEEE Std 802.15.4-2015, chapter 16.4.1, "Operating frequency bands". The table below provides an overview of the supported channels by R&S SMW.

By default, the frame length is 20 octets, that is the data length of the physical header. If you activate the MAC frame check sequence (FCS) field, the frame length increases.
Using the default "MAC FCS Length > 2 Octets", the frame length is 22 octets. If you further activate the MAC header, the frame length increases. Using the default
"MAC Header > 11 Octets", the frame length is 33 octets.

Additional to the built-in filters for custom digital modulation, you can select the default filter type "802.15.4z". This filter is a root-raised cosine filter, that is optimized for
802.15.4z-BPRF and 802.15.4z-HPRF mode. Remote command:
[:SOURce<hw>]:BB:HUWB:FILTer:TYPE on page 77
Optimization
Selects one of the provided EUTRA/LTE filters. Each filter is designed for different application field and optimized for a particular per-
formance. Depending on the filter implementation, these filters require different calcula­tion time. The applied upsampling factor also influences the size of the calculated out­put waveform file.
Waveforms can be calculated in the following ways:
With the "Generate Waveform File" function
With the signal generation software R&S WinIQSIM2
The following table outlines the difference between the provided EUTRA/LTE filters by comparing their major specifications.
Table 4-1: Overview of the EUTRA/LTE filters
Signal generation control
Filter/Clipping/ARB settings
Characteristic "Best EVM" "Best ACP"
"Best ACP (Narrow)"
Design goal An excellent EVM perfor-
mance while ignoring the effects on ACP
Calculation time (in real-time processing)
Upsampling Upsampling with factor 2
Output waveform file size
Recommended appli­cation field
By real-time processing, short calculation time
The sample rate of the output waveform is twice the LTE sample rate
Increased file size Increased file size File size is maintained
Receiver and performance tests with internal real-time generation, where BLER is analyzed
A combination of an excellent ACP performance and a good EVM perfor­mance
"Best ACP (Narrow)" features also a smoother shape in frequency domain
Long calculation time: the filtered sig­nal is precalculated because of the fil­ter complexity
Upsampling with factor 2 The sample rate of the output wave-
form is twice the LTE sample rate The signal processing requires twice
as much internal memory. The availa­ble memory on the instrument is suffi­cient for the simulation of half as many frames compared to filter "Best EVM"
Transmitter and components tests where excellent ACP is required
"Best EVM (no upsampling)"
A combination of an excellent ACP performance and a good EVM performance
Small output waveform file size
Long calculation time: the fil­tered signal is precalculated because of the filter complexity
Upsampling is not applied The sample rate of the output
waveform is not changed
The resulting file size is smaller than in the other cases
Receiver and performance tests with pre-generated waveform files, where BLER is analyzed
In specific configurations, an internal ("Auto") filter is applied automatically. This filter is designed for best possible optimization in configurations, like the carrier aggregation with carriers that span different bandwidths.

Load User Filter
If Filter > "User" is selected, it opens the standard dialog "Select List File" for loading a user-defined filter file.
User filters are used as offline filters. The following types are supported:
Files with predefined file format and extensions *.vaf For information, refer to the description "Introduction to "filtwiz" Filter Editor" on the Rohde & Schwarz web page.
ASCII files with simple format and file extension *.dat These files describe filters as a sequence of normalized filter coefficients. Each coefficient is defined as a pair of I and Q samples. The I and Q components alter­nate at each file line. The I and Q values vary between - 1 and + 1. A user filter can contain up to 2560 coefficients. The user filter must be real-valued. For both I and Q components of the coeffi­cients, only real coefficients different than 0 are allowed. You can create user filter files for example with MATLAB, see Example "Script that
generates user filter file" on page 34.
Example: Script that generates user filter file

Cut Off Frequency Shift
Requires "Filter > Cosine" or "Filter > EUTRA/LTE" and "Optimization > Best EVM". The cutoff frequency is a filter characteristic that defines the frequency at the 3 dB
down point. The "Cut Off Frequency Shift" affects this frequency in the way that the fil­ter flanks are "moved" and the transition band increases by "Cut Off Frequency Shift"*"Sample Rate".
A "Cut Off Frequency Shift" = -1 results in a very narrow-band filter
Increasing the value up to 1 makes the filter more broad-band
By "Cut Off Frequency Shift" = 0, the -3 dB point is at the frequency determined by the half of the selected "Sample Rate".

5 Remote control commands

Remote control commands
The following commands are required to generate signals with the HRP UWB option in a remote environment. We assume that the R&S SMW has already been set up for remote operation in a network as described in the R&S SMW documentation. A knowl­edge about the remote control operation and the SCPI command syntax is assumed.
Conventions used in SCPI command descriptions
For a description of the conventions used in the remote command descriptions, see section "Remote-Control Commands" in the R&S SMW user manual.
Common suffixes
The following common suffixes are used in the remote commands:
Suffix Value range Description
SOURce<hw>
OUTPut<ch>
Using SCPI command aliases for advanced mode with multiple entities
You can address multiple entities configurations by using the SCPI commands starting with the keyword SOURce or the alias commands starting with the keyword ENTity.
Note that the meaning of the keyword SOURce<hw> changes in the second case. For details, see section "SCPI Command Aliases for Advanced Mode with Multiple
Entities" in the R&S SMW user manual.
Programming examples
This description provides simple programming examples. The purpose of the examples is to present all commands for a given task. In real applications, one would rather reduce the examples to an appropriate subset of commands.
The programming examples have been tested with a software tool which provides an environment for the development and execution of remote tests. To keep the example as simple as possible, only the "clean" SCPI syntax elements are reported. Non-exe­cutable command lines (e.g. comments) start with two // characters.
[1] to 4 Available baseband signals
Only SOURce1 possible, if the keyword ENTity is used
1 to 3 Available markers
At the beginning of the most remote control program, an instrument preset/reset is rec­ommended to set the instrument to a definite state. The commands *RST and SYSTem:PRESet are equivalent for this purpose. *CLS also resets the status registers and clears the output buffer.
