Abstract
The present invention relates to a method of reducing equalizer complexity in communication systems, which also provides for reduced power dissipation. The method consists of reducing the number of channel responses expected by the equalizer by averaging sub-groups of all of the possible the channel responses chosen in a particular way.
Claims25
A method for complexity reduction of an equalizer in a communication system comprising the steps of:
- (a) generating a full-length channel response acquisition for symbol patterns equal in length to, or longer than the length of the channel spread;
- (b) reducing the effective set of channel responses by averaging the subsets of appropriate responses;
- and
- (c) using the reduced set of responses of step (b) as a model channel response for lower complexity equalization.
