ABSTRACT:
A transmitter comprising circuitry (14) for converting input bits to a plurality of symbols; and circuitry (24x) for forming a complex conjugate of signals corresponding to selected ones of the plurality of symbols. The selected ones of the plurality of symbols consist of signals corresponding to some and less than all the plurality of symbols. The transmitter also comprises circuitry (28x) for space time encoding both the signals corresponding to the selected ones of the plurality of symbols and signals corresponding to non-selected ones of the plurality of symbols. Lastly, the transmitter comprises a plurality of transmit antennas (TATx) coupled to transmit signals in response to the circuitry for space time encoding.
