Weight generation method for multi-antenna communication systems utilizing RF-based and baseband signal weighting and combining based upon minimum bit error rate

摘要

In a communication system including a transmitter having a set of transmit antennas disposed to transmit a set of spatially-multiplexed RF output signals through a channel, and a receiver having a plurality of receive antennas disposed to generate a corresponding first plurality of spatially-multiplexed received RF signals in response to receipt of said spatially-multiplexed RF output signals, an RF processing method is provided comprising: generating said set of spatially-multiplexed RF output signals by performing a splitting and weighting operation upon plural RF input signals, said splitting and weighting operation utilizing a first set of RF weighting values selected in accordance with one or more output bit error rates of said receiver, and forming a second plurality of spatially-multiplexed received RF signals by performing a weighting and combining operation upon said first plurality of spatially- multiplexed received RF signals, said weighting and combining operation utilizing a second set of RF weighting values selected in accordance with said one or more output bit error rates.
