摘　　要：介绍了同步码分多址 (SCDMA)系统中的迭代多用户检测 (MUD)接收机 ,它是 Turbo译码算法迭代思想的推广 ,迭代多用户检测技术 ,同 Turbo码的译码和多用户检测的研究相结合 ,成为目前通信领域研究的热点。研究结果表明 ,多次迭代后 ,系统性能将得到很大提高 。The paper introduces an iterative multi user receiver for synchronous CDMA system, which derives from Turbo decode algorithm. The iterative multi user detection decoding technology, combined with the research on Turbo decoding and multi user detection, has become a hotspot in communication research field recently. The research shows that iterations of the system are used to attain large performance improvements that are close to single user performance.

关 键 词：TURBO码 同步CDMA系统 多用户检测 迭代算法 MUD
