摘要
Abstract
In this paper a non-blind approach is presented for the multiuser channel identification based on stability of cyclic frequency produced by modulation. It uses the cyclo-frequences induced method to I-dentify the channels of different users. Namely,the second-order statistics of users signal can be separated from multi-user signal by using the difference of cyclo-frequences. The approach is simple with interference rejection capabilities. The simulation results are presented to verify the proposed algorithm. The results show that the algorithm converges fast and has good anti-jamming capability. Also the effectiveness and reliability of the algorithm are verified.关键词
