Abstract

Smart antenna can effectively suppress multipath interference, co-channel interference, and improves the transmission quality of signal and the utilization of spectrum, so it is widely applied in wireless communication network. To explore the optimization problem about smart antenna receiving array and sensor network which exists in radar, sonar and other systems, here we presents a kind of adaptive beam-forming algorithm based on diagonal-loading and mean square error (MSE) criterion. Such a novel algorithm could give the optimal solution of weight direction vector, and at the same guarantees its own robustness. Furthermore, it also possesses the advantage of shortening the convergence time of weight direction vector, and decreasing the sensitive issue of model error in high SNR environment. In our simulation experiments, it is shown that the proposed algorithm improves the performance of receiver network in sonar system, and to a certain extent achieves the signal optimization.
