“…A novel approach of using a multilayer feedforward network was proposed by Kwan and Lee in [4] which resulted in robust performance compared to the previously mentioned techniques. The method used for training the network was Backpropagation (BP) algorithm and the signal code used was Barker code which has the sequence [1, 1, 1, 1, 1, −1, −1, 1, 1, −1, 1, −1, 1].…”
