Abstract
Interference cancellation is implemented for a multiple antenna system. The multiple antenna receiver is provided that includes a whitening filter coupled to receive processed signals corresponding to signals received at respective antennas, and to generate whitened signals corresponding to each of the received signals, having a colored noise component whitened. The whitening filter coupled to determine the whitened signals, at least in part, utilizes symbols corresponding to the signals received by the plurality of antennas. A signal separator is coupled to supply the whitening filter with processed received signals having interference components reduced as compared to received signals.
