摘　　要：提出用TTCM与OFDM相结合的传输体制解决高速数据传输的效率和可靠性问题。简要介绍TTCM技术及符号MAP算法,并比较了二进制MAP算法与符号MAP算法的差别。在此基础上对TTCM与OFDM相结合的体制进行仿真研究,并给出AWGN信道和海上SHF多径信道上的性能结果。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.

关 键 词：TTCM 符号MAP OFDM SHF
