| 摘 要： | 针对多输入多输出线性时不变系统提出了一种新颖的盲辨识方法。该方法利用了调制产生的二阶循环平稳性，在循环频率域对信号的统计量进行分离，最终将各个系统的冲激响应辨识出来。分别讨论了4输入4输出系统在有加性高斯白噪声时的信道辨识情况．并对算法进行了计算机模拟。

| Abstract: | In this paper,a novel approach is presented for the multiple inputs multiple outputs system identification. The approach makes use of the modulation induced second order cyclostationarity, and separates each statistics of the different system, capable of identifying individual sys terns of different user. The authors discussed the identification of channel in the four-in four-out system with additive Gauss white noise respectively. Finally, a simulation of this method is discussed. |
