Abstract: Apparatus and method for generating signal gain coefficients for use in packet data communication between a single-input-single-output (SISO) transceiver and a single-input-multiple-output/multiple-input-single-output (SIMO/MISO) transceiver. Coordinate rotation digital computation (CORDIC) techniques are used to generate transmit channel coefficients which are substantially complementary to 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. Using such transmit channel coefficients to produce outgoing RF signals for transmission via the same antenna elements and reception by such particular SISO RF transceiver provides for signal transmission and reception diversity.
