ADAPTIVE LINEAR ESTIMATION IS A POWERFUL TECHNIQUE FOR RETRIEVING INFORMATION FROM NOISE CORRUPTED SIGNALS WITH UNKNOWN, TIME-VARYING, SIGNAL AND NOISE STATISTICS.

ADAPTIVE LINEAR ESTIMATION IS A POWERFUL TECHNIQUE FOR RETRIEVING INFORMATION FROM NOISE CORRUPTED SIGNALS WITH UNKNOWN, TIME-VARYING, SIGNAL AND NOISE STATISTICS. IT HAS BEEN RARELY APPLIED TO COMMUNICATION APPLICATIONS BECAUSE OF THE PROHIBITIVE COMPLEXITY AND COST OF THE REQUIRED DIGITAL SIGNAL PROCESSING WHEN IMPLEMENTED ON A GENERAL PURPOSE SEQUENTIAL COMPUTER. THIS PROJECT COMBINES PARALLEL PROCESSING CAPABILITY OF VSLI HARDWARE WITH RECENTLY DEVELOPED MODULAR RELIZATIONS OF THE ADAPTIVE MULTICHANNEL LINEAR ESTIMATOR DEVELOP A SPECIAL PURPOSE SIGNAL PROCESSINGCOMPONENT FOR INTERFERENCE SUPPRESSION. THUS COMPONENT HAS HAS DIRECT APPLICATION TO CHANNEL EQUALIZATION NOISE CANCELLING, MULTIPATH CANCELLING, DOPPLER PROCESSING AND NULL STEERING. SEVERAL OF THESE SIGNAL PROCESSING OPERATIONSCAN BE COMBINED IN A SINGLE ADAPTIVE LINEAR ESTIMATOR WITHOUT SIGNIFICANTLY INCREASING ITS COMPLEXITY OR REDUCING ITS PROCESSING SPEED.
