We propose a complex-valued multilayer perceptron (CVMLP) neural network for adaptive beamforming. The complex-valued backpropagation algorithm (CVBPA) has been used to train the network. Experiments for a narrowband signal with multiple beam pointings and multiple nulls steering has been conducted. By using a 7-2-1 CVMLP topology and linear activation function, it is demonstrated that the beamforming by using CVMLP outperforms beamforming using complex-valued least mean square (CLMS) algorithm in terms of faster learning convergence and better interferences suppressions.
