2.2 About DAB/T-DMB
The R&S SMCV100B enables you to generate signals in accordance with the Digital
Audio Broadcasting (DAB)/Terrestrial Digital Multimedia Broadcasting (T-DMB) standard.
The generated signals are compliant with ETSI EN 300 401 standard. Via the userfriendly graphical interface of R&S SMCV100B, you can adjust several DAB signal
parameters. You are enabled to generate a signal corresponding to one of the four
standard transport modes, Transmission Mode I, II, III or IV. You can also choose to
enable or disable channel coding, time interleaving and/or pseudo noise scrambling.
The R&S SMCV100B allows you to choose between different data sources. You can
either use some of the predefined data sources (two different pseudo noise sequences, fixed all “0”, fixed all “1”) or you can use source files that comply with the Ensemble Transport Interface-compliant (ETI) specification. For example, if you are member
of WorldDAB, you can download ETI-compliant source files from the WorldDAB library
available at:
https://www.worlddab.org/resources/worlddab-eti-library
The DAB system is designed for delivery of high-quality digital audio programs and
data services for mobile, portable and fixed reception from terrestrial or satellite transmitters. The system operates in Very High Frequency (VHF)/Ultra High Frequency
(UHF) frequency bands. Also, it is used for distribution through cable networks.
The DAB system is designed to provide spectrum and power efficient techniques in terrestrial transmitter network planning, known as the Single Frequency Network (SFN)
and the gap-filling technique. The DAB system is suitable for satellite and hybrid/mixed
terrestrial/satellite broadcasting, using a simple, nearly omni-directional receiving

antenna. The DAB system meets the required sharing criteria with other radio communication services.
2.2.1 DAB network
The figure bellow illustrates the outline of a DAB network.
Figure 2-1: DAB network
The DAB network has three main parts: the service or service component provider, the
multiplex or ensemble provision and the transmission network provision.
The interfaces between these blocks are scope of ETSI standards. The Service Transport Interface (STI) is defined to provide a standardized way of transporting DAB service components, service information and control messages in a DAB collection network.
About the T-DMB/DAB option
About DAB/T-DMB
The Ensemble Transport Interface (ETI) links the multiplexer of the Ensemble Provider
with the transmitters of the Transmission Network Provider.

and an optional signal s
2.2.3 Transport mechanisms
The DAB system is designed to carry several digital audio signals together with data
signals. Audio and data signals are considered to be service components which can be
grouped to form services.
The DAB system transmission frame consists of three different channels:
●
●
●
2.2.3.1 Transmission channels
The MSC is a time-interleaved data channel used to carry the audio and data service
components, together with possible supporting and additional data service components. The MSC is divided into several subchannels. Each of the subchannels is individually convolutionally coded with equal or unequal error protection. Each subchannel
can carry one or more service components.
(t) as illustrated in the figure above.
TII
Main Service Channel (MSC)
Fast Information Channel (FIC)
Synchronization Channel
About the T-DMB/DAB option
About DAB/T-DMB
The FIC is a non time-interleaved data channel with fixed equal error correction. FIC
carries information about the organization of the MSC subchannels, such as information on the multiplex structure and, when necessary, its reconfiguration. Optionally FIC
can include service information, conditional access management information and data
service.
The Synchronization Channel provides a phase reference and is used internally for
demodulator functions such as transmission frame synchronization, automatic frequency control, transmitter identification, and channel state estimation.
The Synchronization Channel, the Fast Information Channel and the Main Service
Channel form a transmission frame (see Figure 2-3). The MSC occupies the major part
of the transmission frame.
Figure 2-3: DAB transmission frame
Each transmission frame is divided into a sequence of OFDM symbols, each symbol
consisting of several carriers.
11User Manual 1179.1029.02 ─ 05
R&S®SMCVB-K156
The Fast Information Block (FIB) and the Common Interleaved Frame (CIF) are introduced to provide transmission mode-independent data transport packages associated
with the FIC and MSC respectively.
The data, carried in the MSC, is divided at source into regular 24 ms bursts corresponding to the sub-channel data capacity of each CIF. The CIF contains 55 296 bits,
divided at 864 capacity units, 64 bits each.
The FIB is a data burst of 256 bits. The sequence of FIBs is carried by the Fast Information Channel (FIC). The structure of the FIB is common to all transmission modes.
The synchronization channel symbols comprise the null symbol and the phase reference symbol. The null symbols are also used to allow a limited number of OFDM carriers to convey the Transmitter Identification Information (TII).
2.2.3.2 Transport modes
Transmission mode is specific set of transmission parameters (e.g. number of carriers,
OFDM symbol duration). Four transmission modes (i.e. I, II, III and IV) are defined to
allow the system to be used for different network configurations and a range of operating frequencies. Depending on the transport mode, the transmission frame has different organization and length, i.e. the transmission frame is specific to the four transmission modes.
About the T-DMB/DAB option
About DAB/T-DMB

CIFs which are associated with each transmission frame for the four transport modes.

2.2.4 Pseudo noise scrambling
Before convolution encoding, the transmitted signal can be scrambled by a modulo-2
addition with a PRBS.
The PRBS polynomial is of degree 9 and specified as P(X) =x9+x5+1.
The initialization word is applied so that the first bit of the PRBS is obtained when the
outputs of all shift register stages are set to "1".

2.2.5 Convolutional coding
The process of convolution coding is applied at the output of each PN scrambler. The
channel encoding process is based on punctured convolutional coding, which allows
both equal and unequal error protection. Unequal error protection (UEP) is designed
for audio services, equal error protection (EEP) for audio and data services. The sampling frequency is respectively 48 kHz and 24 kHz.
The convolutional coder is a punctured convolution code, based on a mother convolutional code with constraint length 7 and rate 1/4.
The generator polynomials are G1=(1,0,1,1,0,1,1), G2=(1,1,1,1,0,0,1),
G3=(1,1,0,0,1,0,1) and G4=(1,0,1,1,0,1,1).
To avoid the need for additional signaling overhead, the data in the FIC are encoded
with fixed, equal channel coding, with a constant 1/3 coding rate.
The puncturing procedures applied for the coding in the MSC are a combination of protection profile and protection level. There are permissible protection profiles defined for
each of the allowed bit rates. Each protection profile is associated with a protection
level. Protection level 1 is the highest level within the same profile.

encode contributing to the subchannels in the MSC. It is not applied to the FIC.

IP channel settings affect input IP data of the local IP data network. The settings are
independent from the used broadcast standard configuration.
Saving/recalling a certain IP channel or local IP data network configuration is not possible via the broadcast standard-specific functionality.
Use the global save/recall functionality instead, see section "Saving and Recalling
Instrument Settings" in the R&S SMCV100B user manual.
The table below shows the availability of the tab in the broadcast standard configuration.
