Abstract:
A transmitter usable for wireless communication includes a plurality of transmit antennas. Each transmit antenna transmits a transmit signal. The transmitter also includes means for introducing time shifts to each of a plurality of spatial stream signals and means for operating on each of the plurality of spatial stream signals with a spatial rotation vector matrix, thereby mapping each of the plurality of spatial stream signals to one of the transmit signals.
