Efficient evaluation of probabilities of detection and the generalized Q-function (Corresp.)
D.A. Shnidman · IEEE Transactions on Information Theory · 1976
A highly efficient method of evaluating probabilities of detection and the generalized\cal Q-function to within an absolute accuracy\epsilonis presented. Many unnecessary computations are avoided when it can be determined by Chernoff bounds that the desired function is within\epsilonof 0 or 1. When this is not the case, efficient algorithms for the necessary computations are also provided.
