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:

  • 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;

    determining weights for estimating each of M×

    N single-input/single-output channels between transmit and receive antennas based on jointly processing pilot symbols received on all of the N receive antennas;

    estimating the M×

    N single-input/single-output channels based on the determined weights; and

    using the estimated channels to determine the information symbols.
