Claim One:
1. A method for receiving a radio communication sent by a transmitter having M transmit antennas to a receiver having N receive antennas, where M is a positive integer greater than or equal to one and N is positive integer greater than one, the method comprising: (a) receiving N output signals, one for each receive antenna, where a signal transmitted from each of M transmit antennas includes predetermined pilot symbols known by the receiver and information symbols to be determined by the receiver; (b) determining a noise-plus-interference correlation matrix associated with the noise-plus-interference at the N receive antennas; (c) determining weights of an adaptive filter based on jointly processing pilot symbols received on the N receive antennas and the noise-plus-interference correlation matrix; (d) estimating each of M×N single-input/single-output channels between transmit and receive antennas based on the determined weights of the adaptive filter; (e) using the estimated channels, the pilot symbols, and the noise-plus-interference matrix to determine the information symbols; (f) using the received signals, the pilot symbols, and the estimated channels to update the noise-plus-interference correlation matrix; and (g) repeating steps (b)-(e) using the updated noise-plus-interference correlation matrix, wherein the adaptive filter changes using the updated noise-plus-interference correlation matrix.
