Abstract: One or more aspects of the disclosure provide an efficient equalization scheme capable of mitigating multi-path interference on channels with large delay spread using short-length equalizers. That is, by dividing stored samples of a signal received on the multi-path channel by time into a plurality of clusters, a short-length equalizer can be utilized in an iterative fashion on each of the clusters, thus eliminating the need for a large length equalizer while still providing improved performance over that of a Rake receiver at large delay spreads. Other aspects, embodiments, and features are also claimed and described.
