Patent ID: 7505741

Claim:
A system for processing receive diversity signals, comprising: a plurality of antennas operable to: receive a downlink signal, the downlink signal comprising information; and generate a plurality of diversity signal associated with the downlink signal, each of the plurality of antennas operable to generate a diversity signal of the plurality of diversity signals; a plurality of filters, each filter of the plurality of filters coupled to an antenna of the plurality of antennas and operable to filter each of the diversity signals received from the plurality of antennas; a delay module coupled to at least one of the plurality of filters and operable to apply a delay to at least one of the plurality of diversity signals, the delay being less than one chip duration, the delay comprising a delay of 0.4 to 0.8 microseconds; an antenna combiner operable to: sum the plurality of diversity signals after applying the delay; and yield a combined signal comprising the delayed at least one of the plurality of diversity signals; an analog-to-digital converter operable to convert the combined signal from analog mode to digital mode; and a processor coupled to the delay module and operable to process the combined signal using the delay to obtain the information, the delay operable to allow at least one multipath signal associated with the downlink signal to be distinguishable, the processor comprising a baseband processor, the baseband processor comprising: a rake receiver module operable to: separate the combined signal in the time domain to yield a plurality of fingers, the plurality of fingers corresponding to the plurality of diversity signals, at least one finger of the plurality of fingers comprising the delay; and coherently combine the plurality of fingers to yield a combined symbol signal, the combined symbol signal corresponding to the downlink signal; and a decoder coupled to the rake receiver module and operable to decode the combined symbol signal to generate the information.
