Abstract : The problem of detecting and identifying multiple signals which are corrupted by independent additive noise is mathematically formulated. It is explicitly assumed that (1) the epoch and time duration of the signals are known, (2) the statistics of the corrupting noise are known, (3) the number of signals and their individual shapes are not known, and (4) the a priori probabilities of the occurrence of the individual signals are not known. An adaptive technique is developed to determine (1) the number of signals, (2) the signal shapes, and (3) the relative frequency of each signal's occurrence. The adaptive procedure uses only the observations made at the receiver output. Computer simulated results are given for the case of Gaussian noise. These results clearly indicate that approximate detection and identification can be achieved adaptively. (Author)
