| 摘 要： | 研究了Turbo码与网格编码调制(TCM)相结合的Turbo-TCM技术,将Turbo码中三类奇偶交织器的设计分别应用到Turbo-TCM中,并在Awgn信道和Rayleigh衰落信道下,对采用三种不同交织方式、不同帧长Turbo-TCM的性能进行了仿真。仿真结果表明,短帧条件下,Awgn信道中采用确定性奇偶交织器的Turbo-TCM性能最优,而Rayleigh衰落信道中三种交织方式的Turbo-TCM性能相近。长帧条件下,Awgn信道和Rayleigh衰落信道中,基于随机奇偶交织器的Tur-bo-TCM性能最优。

| Abstract: | In this paper,we discuss the modulation techniques for combing turbo code with TCM,and apply three kinds of even-odd interleavers to Turbo-TCM.Then we simulate the performance of Turbo-TCM in Awgn and Rayleigh channels which use three different kinds of interleavers and different length of frame.The results show that,under condition of short frame,in Awgn channel,Turbo-TCM which use deterministic even-odd interleaver have best performance;in Rayleigh channel,the performances of Turbo-TCM based on three types of interleavers are similar.Under condition of long frame,in Awgn and Rayleigh channels,the performances of Turbo-TCM which use random evenodd interleaver have best performance. |
