摘要： Systems and methods that provide antenna selection in multi-antenna-element communication systems are provided. 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 transmit weighting values (514) for signal weighting that may be used in various transmitter and receiver structures is disclosed herein. The weighting values are determined as a function of frequency based upon a state of a communication channel (512) and the transmission mode of the signal. In variations, weighting of the weighted signal that is transmitted through each of a plurality of antennas is carried out with one of a corresponding plurality of transmit antenna spatial weights (522). In these variations, a search may be conducted over various combinations of transmit weighting values and transmit antenna spatial weights in order to find a weight combination that optimizes a performance measure such as the output signal-to-noise ratio, the output bit error rate or the output packet error rate.

摘要： A signal weighting and combining method implemented within a receiver (520) having a plurality of receive antennas (560) 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 (550). The method includes weighting (534) the plurality of received RF signals produced by the antennas in accordance with a corresponding plurality of RF weighting values selected to minimize an output bit error rate of the receiver, 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 (510) having a plurality of transmit antennas (522) is also disclosed.
