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.

• 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。
