摘　　要：用传统检测器的输出来初始化独立分量分析(ICA)的迭代,利用多用户信号的已知信息,克服了ICA的不确定性问题,也充分利用了多用户信号的统计独立性。仿真实验结果证明这种多用户检测算法在高信噪比的情况下,误码性能改善随着信噪比的提高不断增加。In order to overcome the uncertainty of ICA problem and take full advantage of the statistical independence of the many users signal, the traditional detector output is used to initialize the iterative of ICA and the known information of multi-- user is also used. The simulation results show that the bit error performance improvement of this multi-- user detection algorithm in high--noise environment increases with the improved SNR.
