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