An optimum multilayer perceptron neural receiver for signal detection

The M-input optimum likelihood-ratio receiver is generalized by considering the case of different signal amplitudes on the receiver primary input lines. Using the more general likelihood-ratio receiver as a reference, an equivalent optimum multilayer perceptron neural network (or neural receiver) is identified for detecting the presence of an M-dimensional target signal corrupted by bandlimited white Gaussian noise. Analytical results are supported by Monte Carlo simulation runs which indicate that the detection capability of the proposed neural receiver is not sensitive to the level of training or number of patterns in the training set.
