About the HRP UWB Option
HRP UWB Signal Properties
The equipment layout for generating HRP UWB signals includes:
●
Baseband Generator (R&S SMM-B9)
●
Option HRP UWB (R&S SMM-K149)
●
Option baseband extension to 240 MHz RF bandwidth (R&S SMM-K523)
●
Option baseband extension to 500 MHz RF bandwidth (R&S SMM-K524)
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 SMM-K255 for
playing LTE waveforms
●
If supported, install the real-time option of the digital standard, e.g. R&S SMM-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.

About the HRP UWB Option
HRP UWB Signal Properties
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.

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 admissible values for the preamble timing parameters that result from the different
code lengths and pulse repetition frequencies are defined in IEEE Std 802.15.4-2015,
chapter 16.2.4, "Preamble timing parameters".

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 SMM100A.

HRP UWB Configuration and Settings
Frame Configuration Settings
An internally generated sequence containing 0 data or 1 data.
●
"PNxx"
An internally generated pseudo-random noise sequence.
●
"Pattern"
An internally generated sequence according to a bit pattern.
Use the "Pattern" box to define the bit pattern.
●
"Data List/Select DList"
A binary data from a data list, internally or externally generated.
Select "Select DList" to access the standard "Select List" dialog.
– Select the "Select Data List > navigate to the list file *.dm_iqd > Select" to
select an existing data list.
– Use the "New" and "Edit" functions to create internally new data list or to edit
an existing one.
– Use the standard "File Manager" function to transfer external data lists to the
instrument.
