%X In this paper, a novel approach is presented for the multiuser channel identification. The approach makes use of the modulation-induced cyclostationarity and its capable of identifing individual channels of different users. By measns of the complex cepstrum of cyclic autocorrelaton, the blind estimation of the channelcan be achieved. The appraoch is rather simple, with considerable advantages. The identifiability condition and its proof are also concluded in the paper. Finally, the simulaton of identification algorithm demonstrates its convergence.
