Abstract :
In previous works the authors introduced the Neural Network (NN) Direction of Arrival(DoA) estimation method for a switched-beam DS-CDMA system. In this paper the method´s performance has been significantly improved, enabling its application not only to the desired signal´s main path but also to its strong multipaths.
