摘　　要：迭代多用户检测技术是Turbo译码算法中的精髓“迭代思想”的又一个应用 ,它结合了turbo码的译码和多用户检测的研究 ,成为目前通信领域研究的热点。结果表明 ,多次迭代后 ,系统性能将得到很大提高 ,接近单用户的性能。Iterative multi-user detection technology is another application of 'iterative thought' which derived from turbo decode algorithm. The iterative multi-user detection decoder considers turbo decode and multi-user detection jointly, which has become a focus in communication research recently. The result is indicated that iterations of the system are used to attain large performance improvements, which is near single user performance.
