Macro diversity equalization system and method
Abstract
An equalization system and method which supports macro diversity as well as large delay spread channels with a minimal increase in complexity is disclosed. The equalization system includes a path searcher, an optional search scheduler, a multi-equalizer manager, an alignment buffer, a plurality of equalizers and an equalizer combiner. The path searcher detects positions of paths of the received signals. The equalizers are used to perform equalization on the received signals. The multi-equalizer manager controls the equalizers by assigning specific positions of the paths to respective ones of the equalizers. The equalizer combiner then combines outputs from the equalizers.
