发明名称 RECEIVER, RECEIVING DEVICE, AND METHOD FOR TERRESTRIAL MOBILE MULTIMEDIA BROADCASTING
摘要 <p>A receive for Terrestrial Mobile Multimedia Broadcasting T-MMB, includes a ratio frequency demodulation unit, for carrying out radio frequency demodulation for a received signal; a synchronization unit, for identifying the transmission mode and the synchronous position of the signal from the radio frequency demodulation unit; an OFDM demodulation unit, for extracting a phase reference symbol. Fast Information Channel FIC symbols and dada symbols from the signal which is from the radio frequency demodulation unit according to the transmission mode and the synchronous position, carrying out OFDM demodulation and decoding for the FIC symbols to obtain FIC information, carrying out OFDM demodulation for the data symbols of the corresponding sub-channel according to the sub-channel indication information; and a demodulation and decoding unit, for carrying out differential demodulation for the data symbols after the OFDM demodulation, carrying out time-domain deinterleaving for the data symbols after differential demodulation according to the indication of the FIC information, and carrying out forward error correction decoding for the data symbols after the time-domain deinterleaving. The invention also discloses a receiving device and a receiving method for T-MMB.</p>
