Abstract:
1. In a receiver having a plurality of receive antennas disposed to produce a corresponding plurality of spatially-multiplexed received RF signals in response to receipt through a channel of spatially-multiplexed transmitted RF signal energy, a signal weighting and combining method comprising: weighting first and second of said plurality of spatially-multiplexed received RF signals respectively in accordance with first and second RF weighting values selected in accordance with one or more output bit error rates of said receiver, thereby forming first and second paired single-weight RF signals; weighting third and fourth of said plurality of spatially-multiplexed received RF signals respectively in accordance with third and fourth RF weighting values selected in accordance with one or more output bit error rates of said receiver, thereby forming third and fourth paired single-weight RF signals; combining said first and second paired single-weight RF signals in order to form a first combined signal and combining said third and fourth paired single-weight RF signals in order to form a second combined signal; and processing said first combined signal using a first RF chain and processing said second combined signal using a second RF chain.
