Signal detection for neural network-based antenna array

This paper considers the application of radial basis neural network with exact solution (RBE) for signal detection stage in antenna array direction of arrival estimation problem. When there is a possibility of a large number of neurons in the hidden layer a good choice for radial basis network in the signal detection stage is to apply Probabilistic Neural Network (PNN). However, for faster network response RBE is a good alternative. Compared to PNN it demands larger number of antenna elements and larger number of training samples in order same results to be achieved. Nevertheless when the network response time is important RBE is superior, since it is couple of times faster.
