A CODING CRITERION FOR CONTINUOUS CHANNELS DERIVED FROM LIKELIHOOD ESTIMATION
Abstract
The divergence between hypotheses is investigated as a criterion for signal selection, and is shown to be useful whenever the probability of error cannot be directly evaluated. After a brief discussion of the divergence in hypothesis-testing problems, the relation between the divergence and the information transfer of the channel is determined. As an illustration of the use of the divergence as a coding criterion, the criterion is applied to a finite set of known signals in additive noise. The divergence is evaluated for this example and compared with the probability of error in a maximum-likelihood receiver. (Author)
