ABSTRACT:
Apparatus and method for providing for packet data communication between a single-input-single-output (SISO) transceiver and a single-input-multiple-output/multiple-input-single-output (SIMO/MISO) transceiver. Receive channel coefficients representing relative strengths of individual signals received via multiple spatially diverse antenna elements and corresponding to a wireless data signal originating from a particular SISO radio frequency (RF) transceiver are used to provide substantially complementary transmit channel coefficients for use in producing outgoing RF signals to be transmitted via the same antenna elements for reception by such particular SISO RF transceiver.
