| 摘 要： | 对 Ｔｕｒｂｏ码的 ＲＳＣ分量码、交织器、调制方式、信道以及迭代译码算法进行了综合研究与性能分析，并给出了一种基于逐比特ＭＡＰ算法的Ｔｕｒｂｏ编码与多元调制相结合的编码调制方式。仿真结果表明，该方案将Ｔｕｒｂｏ码的高编码增益与多元调制的高频谱利用率有效地结合在一起，是一种功率和频谱高效的编码调制方式，比传统的ＴＣＭ方式有更好的性能。

| Abstract: | The paper makes researches on the corn it RSCs, interleavcr, modulation modes, channels, and iterative decoding algorithms in Turbo codes, ~3nd presents a new Turbo coded modulation sch me, using a bit - by - bit MAP algorithm. Simulation results show that this coded modulation scheme, which corn-hines the large coding gain of Turbo codes with the high bandwidth efficiency of M - ary modulation, is power and bandwidth efficient. |
