The recovery of input signals in a frequency selective fading channel is a problem of great theoretical and practical interest. In this paper, we present several new blind algorithms that utilize second order statistics for multichannel equalization. The algorithms are based on the subspace extraction of a preselected block column of the channel convolution matrix. For multiuser system, user signal separation can be achieved based on partial information of the composite channel response. The… CONTINUE READING
