| 摘 要： | 讨论了通信系统中常用的ICA算法,并用性能指数对算法的性能进行了评估.独立分量信号用亚高斯信号、超高斯信号描述,将若干个独立分量信号进行线性混合以此来模拟通信系统中的信号.实验结果显示JADE-ICA的算法性能指数最低,性能最好,是通信系统较好的选择.

| Abstract: | This paper evaluates the performance of some major ICA algorithms,separation performance of ICA algorithms measure by performance index.Independent signals representing sub-Gaussian.gaussina and mix users.are generated and then mixed linearly to simulate communication signals.The result of experiment show that the PI of JADE-ICA is the smallest and has best performance and is abetter choice for communication system. |
