Abstract|Using performance analysis of Reduced State Sequence Estimators RSSE, we characterize dominant error events for a Noise Predictive Maximum Likelihood NPML detector. The error event characterization may be used to determine distance enhancing constraints that improve the reliability o f NPML RSSE detection. An example of a constraint that provides approximately :8 dB asymptotic coding gain for an NPML detector operating at a user bit density o f 2 : 54 is illustrated.
