This paper presents a detector for obtaining MLSD decisions on binary symbols that has been corrupted by intersymbol interference and additive Gaussian noise. The basis of the detector is a bound on a cross-product of the quadratic form in the log-likelihood function for the transmitted sequence. The detector will only make decisions on some of the symbols in a transmitted sequence, but those decisions will be the same decisions as the MLSD would have made. The number of symbols to be detected is stochastic, varying from sequence to sequence. The detector is simple in structure, consisting of a whitened matched filter and two variable thresholds for each symbol to be detected. Because the detector in general does not detect the complete sequence of symbols, but has a very good performance on those symbols that are detected, it is suitable as a complement to some existing detector that is inferior to the maximum likelihood sequence detector.
