摘　　要：本文利用了一种新的调制频率和循环频率的分配方法,提出了一种基于循环平稳特性的新颖的多用户信道盲辨识方法。该方法运用调制引入循环平稳特性来区分每个用户的二阶循环统计量(CSOCS,Cyclic Second-Order Cyclic Statistics),能够识别不同用户的单个信道。仿真结果证明该算法是可行的。In this paper, a novel approach is put forward for the multiuser channel identification. The approach makes use of the modulation-induced cyclostationarity to separate the second order cyclic statistics for every user, being able to identify individual channels of different users. And finally the identification algorithm is proposed with simulation results.
