1. A method comprising:

  • receiving at a receiving device a wireless communication that includes a transmitted block of symbols transmitted from at least two space diverse antennas, the transmitted block of symbols being received at the receiving device over at least first and second transmit channels that couple the at least two space diverse antennas to the receiving device, the transmitted block including a first symbol and a complex conjugate of the first symbol and a second symbol and a negative complex conjugate of the second symbol, the first symbol and the complex conjugate of the first symbol being received over different ones of the first and second transmit channels, and the second symbol and the negative complex conjugate of the second symbol being received over different ones of the first and second transmit channels;

    wherein the receiving of the transmitted block of symbols includes receiving the first symbol and the complex conjugate of the first symbol with one of frequency diversity or time diversity; and

    wherein the receiving of the transmitted block of symbols further includes receiving the second symbol and the negative complex conjugate of the second symbol with frequency diversity if the first symbol and the complex conjugate of the first symbol are received with frequency diversity and receiving the second symbol and the negative complex conjugate of the second symbol with time diversity if the first symbol and the complex conjugate of the first symbol are received with time diversity.
