| Abstract: | In this paper a novel approach is presented for the multiuser channel identification.It makes use of the modulation-induced cyclostationarity and the incompatibility of cyclic frequencies to separate each channel's statistics. Each user's cyclic crosscorrelation can be extracted from distinctness of cyclic frequencies.Then each channel of different users can be identified by means of the simple single-channel method.The simulation results demonstrate its effectiveness against noise and multiuser interferenc... |
