Theory of Signal Detectability: Adaptive Optimum Receiver Design
The theory of adaptive optimum receiver design is presented and its relationship to the classical theory of signal detectability of Peterson, Birdsall, and Fox is presented. The classical theory concentrated on the function description; i.e., the optimum detector for a fixed observation procedure is one that forms the likelihood ratio. Optimum detection performance depends on this inputâ€ output relationship. This paper concentrates a more detailed description of the optimum detector; i.e., its realization or implementation. It is shown how optimum detectors can be implemented in a sequential manner, resulting in a receiver configuration that is adaptive. The sequential nature of the adaptive implementation is one in which both a classification and detection output is readily available and, in addition, the design is such that the terminal time of the observation need not be known a priori. The adaptive optimum receiver design theory stresses the use of the receiver memory. © 1967, Acoustical Society of America. All rights reserved.
