WebbIn the Sync Signal Search subsystem, the SearchHold signal disables maximum peak search until it estimates the carrier frequency offset. The SSPeakSearchDone signal goes high after the completion of peak search in each OFDM frame duration. For an FFT Length of 128, the frame duration is 5760 samples.
