NORMALIZED LEAST MEAN SQUARE CHIP-LEVEL EQUALIZATION ADVANCED DIVERSITY RECEIVER |
摘要 |
<p>A receiver which includes at least one equalizer filter and a tap coefficients generator for implementing receive diversity. The equalizer filter processes a 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 generated by 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 the antennas. In yet another embodiment, the sample data streams are combined after being processed by a plurality of matched filters based on respective estimated channel impulse responses.</p> |
