About ISDBT Baseband VerificationLibraryThe Agilent EEsof ISDB-T Design Library is provided for the Japanese digital videobroadcasting market. This design library follows ARIB STD-B31 V1.6 [1], ARIB STD-B29v2.2 [2] and ARIB STD-B46 V1.0 [3]. This design library focuses on the physical layer ofISDB-T systems and is intended to be a baseline system for designers to get an idea ofwhat a nominal or ideal system performance would be. Evaluations can be made regardingdegraded system performance due to system impairments that may include nonidealcomponent performance.

ISDB-T System

An ISDB-T signal shall be transmitted in a channel of 6 MHz bandwidth, with totally1.13 OFDM segments. Each OFDM segment transmits one data segment, continuouspilots, scattered pilots, TMCC and auxiliary information.This channel-coding scheme allows hierarchical transmission in which multiple2.hierarchical layers with different transmission parameters can be transmittedsimultaneously. Each hierarchical layer consists of one or more OFDM segments.Parameters such as the carrier modulation scheme, inner-code coding rate, and timeinterleaving length can be specified for each hierarchical layer. In the configurationthat contains one-segment service, a center OFDM segment of TV signal can be alsoreceived by a digital sound broadcasting receiver. Up to three hierarchical layers canbe transmitted. Figure below shows conceptual drawings of hierarchical transmissionand partial reception.

Frequency interleavingFrequency interleaving is block-interleaving that is applied to data sub-carrierswithin an OFDM symbol. It consists of inter-segment interleaving and intra-segment interleaving.

Inter-segment interleavingInter-segment interleaving is not conducted on the partial-receptionsegment (No. 0).Inter-segment interleaving is conducted on two or more datasegments when they belong to the same type of modulated portion,even if their hierarchical level differ (For example, if layer A has 5segments and is QPSK modulated, layer B has 13 segments and is16QAM modulated, then inter-segment interleaving shall be conductedamong the 13 segments).Arrangement of symbols before and after interleavinginput S0, S1, ..., SNc-1 SNc, SNc+1, ..., SNc*2-

segment interleaving.Carrier randomizingThe carrier randomizing is applied based on the following mappingalgorithm

Connected transmission5.

Connected transmission is defined as the transmission of multiple signals(i.e. ISDB-Tsb signal and ISDB-T signal) from the same transmitter with no guard band. Inconnected transmission, each signal branch are independently channel coded,modulated and adapted to form their own OFDM segments as normal (without addingthe rightmost CP). After OFDM segment adaptation, all segment symbol data areadapted for OFDM-signal generation by a single IFFT. In this case, the first sub-carrier of upper adjacent segment can be treated as a SP signal of the desired


16

segment, so only one CP is added to the right side of the rightmost segment.Phase compensation for the difference of center frequency.Assuming the center frequency of a desireed ISDB-Tsb/ISDB-T signal in a connectedtransmission is fr, and the center frequency of the connected transmission band is ft.When a receiver filtering out the desired signal and down-convert the signal with alocal carrier whose center frequency is fr, a phase rotation of Φ=-(fr-ft)*TGI will be

introduced between consecutive OFDM symbols due to the guard interval insertion.The phase rotation is compensated in the transmitter side. The amount of phasecompensation is

Φ(δf) = 2π * δf * GIR * 2Mode

where δf=(fr-ft)/(the bandwidth of one OFDM segment), GIR is guard interval ratio,Mode is 0, 1, and 2 for Mode 1, Mode 2 and Mode 3 respectively.The phase rotation amounts to 2nπ every 8-symbol period. Accordingly, at the firstsymbol of a frame in which the synchronization word of TMCC is W0, the amount ofphase rotation is prescribed as 0.Phase compensation for the phase difference of pilot carrier modulation.The first sub-carrier of the upper adjacent segment can be treated as a SP of thedesired segment when super segments are connected. The first PRBS Wi1 (0 or 1) inthe upper adjacent segment and rightmost PRBS Wi2 which is corresponding to CP inthe desired segment can be unmatched. In this case, the phase of the upper adjacentsuper segment are rotated by π to make Wi2 and Wi2 match.Phase compensation in reception.When desired segment (1 segment or 13 segments) uses the first carrier of adjacentupper segment as a reference signal (SP), the phase of that carrier should be rotatedevery OFDM symbol with the amount of Φ(n) = δΦ*n, where n is the OFDM symbolindex in two consecutive OFDM frames, δ/2π should be selected in accordance withthe table shown below.

At the first symbol of a frame in which the synchronization word of TMCC is W0, theamount of phase rotation is prescribed as 0 and so the OFDM symbol index n is 0.

Notes/Equations

This model takes the output of FFT as input to estimate the channel frequency response(CFR) introduced by radio propagation environment.

AlgorithmsScattered pilots are picked up from input symbols and then de-randomized witha PRBS sequences defined in ISDB-T OFDM Frame Structuring (isdbtbasever).CFRs are then estimated in the pilot locations by dividing the de-scrambled inputdata with 4/3.Time domain linear interpolation are applied to get a CFR sequence with ainterval of 3 sub-carriers.Frequency linear or Wiener interpolation are applied to get the CFR of all sub-carriers.For differential modulation segments, the CFR is output as 1.

Parameter detailsFirstSymIndex specify the index of first input symbol in two consecutive OFDMframes. FirstSymIndex%4 is used to determine the SP locations andFirstSymIndex%8 is used to determine the phase compensation of upmost pilotin connected transmission. To simplify implementation, the rightmost pilot isalways regarded as an SP.SYNC 0 SYNC 1

SYM 0 SYM 1 ... SYM 203 SYM 204 SYM 205 ... SYM 407

PhaseCorrection must be specified according to ISDB-T ConnectedTransmission (isdbtbasever).SubChNumOfSeg0 This is used to determine the initialization value of PRBSsequence.CIRAdjustRatio This is used to compensate the phase shift introduced byadjusting FFT window. Generally it should be less than GI_Size/FFTSize.

Notes/Equations

This model searches the peaks from the output of the ISDBT_MLCorrelator for theMaximum-Likelihood synchronization of CP based OFDM system.

The peak should be lies in the range of SearchRange.An optimized peak index (OFDM symbol edge index in an input block of NFFT+NGI

samples) is obtained by averaging the SymsToAverage peak indices.An optimized frequency offset is obtained by averaging the angles at theSymsToAverage peak indices. The frequency offset is normalized by sub-carrierspacing, i.e.

ξ = (FcTx-FcRx)*TFFT

Where Fc is the center frequency of up-convertor/down-convertor oscillator.If SyncTrack is NO, the output peak index and frequency offset shall remains thesame after the first averaging. If SyncTrack is YES, the output peak index andfrequency offset shall be recalculated if the distance between real-time peak index inthe recent input samples and the optimized peak index are larger thanTimingTolerance SyncLoseThreshold times.

Notes/Equations

This model demodulates the baseband ISDB-T three-layer signal.



I/O detailsConstellation outputs the equalized sub-carriers (including data, pilots, TMCCand ACs) in segment sequence of 0,1,...12 (Layer A followed by Layer B).Rightmost CP is not included.RSDecInA, RSDecInB and RSDecInC can be used to measure the BERperformance of Viterbi decoding.RSDecOutA, RSDecOutB and RSDecOutC can be used to measure the BERperformance of RS decoding.

Notes:SegmentsA must be 1, and SegmentsA+SegmentsB+SegmentsC must be 13.Frame head of the input ISDB-T signal must be within the first [0,NFFT] samples,

otherwise the output may be incorrect due to pilot pattern synchronizationfailure.To connect the outputs with the corresponding reference signals from the signalsource, demodulation/decoding delays must be considered. To get the delay
