A wireless receiver (30.sub.1) for receiving multiple space time encoded
signals from a plurality of transmit antenna sets (TAT.sub.1 through
TAT.sub.2, and TAT.sub.3 through TAT.sub.4), wherein the multiple space
time encoded signals comprise a set of symbols and wherein each transmit
antenna set is coupled to a corresponding encoder (22.sub.1, 22.sub.2) at
a single transmitter (12.sub.1). The receiver comprises a plurality of
receive antennas (RAT.sub.1 through RAT.sub.Q) and collection circuitry
(32), coupled to the plurality of receive antennas, for collecting a
plurality of signal samples for a plurality of successive time instances
and from each of the plurality of receive antennas. The collected samples
comprise samples of multipaths of the space time encoded signals. The
receiver also comprises circuitry (34, 36), coupled to the plurality of
receive antennas, for determining a linear time invariant multiple-input
multiple-output matrix in response to pilot values in the received
multiple space time encoded signals. Finally, the receiver comprise
circuitry (40, 42.sub.1, 44.sub.1) for estimating at least selected ones
of the symbols in response to the signal samples and the linear time
invariant multiple-input multiple-output matrix.
