摘要：

We consider a multiuser OFDM system, and propose a novel approach for blind channel estimation. Each user information signal is linearly precoded before OFDM modulation. The receiver uses an antenna array. Using crosscorrelations of the blocks received at the array elements, leads to estimation of the underlying channels within a scaling ambiguity.
