【Abstract】 A data transmission system combines TTCM and OFDM which achieve high efficient and reliability is presented in this paper. First it introduces TTCM and MAP algorithm and then compares the difference between binary MAP and Symbol by Symbol MAP. The BER performance is studied under AWGN and SHF multipath fading channels. The simulation result is also given in this paper.更多还原
