<p>A receiver which includes at least one equalizer filter and a tap coefficientsgenerator for implementing receive diversity. The equalizer filter processesa signal derived from signals received by a plurality of antennas. In one embodiment,sample data streams from the antennas are merged into one sample data stream.The merged sample data stream is processed by a single extended equalizer filter,whereby filter coefficients are adjusted in accordance with a joint error signal.A filter coefficient correction term used by the equalizer filter is generatedby the tap coefficients generator using a normalized least mean square (NLMS)algorithm. In another embodiment, a plurality of equalizer filters are utilized,whereby each equalizer receives a sample data stream from a specific one of theantennas. In yet another embodiment, the sample data streams are combined afterbeing processed by a plurality of matched filters based on respective estimatedchannel impulse responses.</p> |
