Abstract :
A novel approach is presented for the multiuser channel identification. The approach makes use of the modulation-induced cyclostationarity (MIC), capable of identifying individual channels of different users. By means of the complex cepstrum of cyclic autocorrelation the blind estimation of the channel can be achieved. The identifiability condition is also presented in the paper. And finally the simulation of identification algorithm is given.
