摘要： A method for processing communication signals is disclosed and may include, in a receiver and/or a baseband processor coupled to the receiver, the receiver comprising a plurality of antennas, generating a plurality of RF weighting values based on one or more output bit error rates of the receiver. A plurality of spatially-multiplexed RF signals, which are received by the receiver, may be weighted with the one or more of the generated plurality of RF weighting values, to form a plurality of weighted RF signals. Two or more of the generated plurality of weighted RF signals may be combined to form one or more combined RF signals. Each of the one or more combined RF signals may be processed by a different RF processing chain. The one or more output bit error rates of the receiver may be minimized by the generation of the plurality of RF weighting values.

摘要： A signal weighting and combining method implemented within a receiver having a plurality of receive antennas is disclosed herein. Each receive antenna is disposed to produce a received RF signal in response to a transmitted RF signal received through a channel. The method includes weighting the plurality of received RF signals produced by the antennas in accordance with a corresponding plurality of RF weighting values selected to maximize an output signal-to-noise ratio of the receiver averaged over the channel, thereby forming a plurality of weighted RF signals. The method further includes combining ones of the plurality of weighted RF signals in order to form one or more combined RF signals. A similar splitting and weighting method capable of being implemented within a transmitter having a plurality of transmit antennas is also disclosed.

In one embodiment, a system that selects N antenna elements in an M-antenna-element transmitter or an M-antenna-element receiver, in which N is less than M, may include, for example, M antenna elements in the M-antenna-element transmitter or the M-antenna-element receiver; N RF chains; and a switch coupled to the N RF chains. The M-antenna-element receiver may determine a bit error rate for each possible N antenna element subset of the M antenna elements. The M-antenna-element receiver may determine the particular N antenna element subset with a lowest bit error rate. In response to the determination of the particular N antenna element subset with the lowest bit error rate, the switch may couple the N RF chains to the particular N antenna element subset with the lowest bit error rate.

摘要： A system and method for generating weight values based on maximum data rate for weighting elements included within signal weighting and combining arrangements used in various multi-antenna transmitter and receiver structures is disclosed herein. Weighting values for a given signal combining arrangement are set so as to maximize an output data rate of the applicable multi-antenna system in the presence of adaptive bit loading of the subcarriers of a transmitted signal. The disclosed techniques may be employed to maximize a data rate of a multi-antenna communication system by using adaptive bit loading and RF and baseband weighting schemes. In this case a search is conducted over various combinations of RF and baseband weights in order to find the weight combination which, when adaptive bit loading is also employed, maximizes the data rate.
