A COMPARISON OF THREE SUBOPTIMUM DETECTORS FOR BINARY SIGNALLING

摘要

The penalties incurred in using the Sampleand-Sum,Weighted Partial Decision and Binary Partial Decision detectors are analyzed.Even though these schemes are inferior to the Digital Matched Filter detector,they could be used in systems with more modest computational capabilities.Analytic expressions for the losses when the number of samples M is large,are obtained.Examples are also given which indicate how these losses vary with M.The effects of oversampling on the penalties are also illustrated.
