Blind MIMO Channel Estimation Based on Modulation-Induced Two-Cycle Cyclostationarity

摘要

In this paper, a novel approach is presented to the multiuser channel identification . The approach makes use of the modulation-induced Cyclostationarity, capable of identifying individual channels of different users. By means of the decomposition of the cyclic spectrum method, the blind estimation of the channel can be achieved . The approach is rather simple, with considerable advantages over existing techniques, and suitable for the multiuser uplink . The identifiabilily condition and its proof are also concluded in the paper. And finally the. simulation of identification algorithm is given.
