摘要：

Meyer and Weinert [1] use the majority rule for fault-tolerant signal detection. We extend this, and examine a redundant system with a general voting rule. We present an optimal design of each individual processor, and the optimal selection of the k-out-of-M voting rule. We give an analytic solution to the optimal voting policy for the special case of low false alarm, with arbitrary failure probabilities and receiver operating characteristics (ROC—s). Performance is improved significantly by using the optimal voting rule instead of the majority voting rule, especially in the tail regions of the ROC. © 1990 IEEE
