    Abstract: This study presents a particle swarm optimization algorithm to optimize the performance of the smart antenna system. All particles of the population are assessed to cost function chosen to be equal to the mean square error between the array output signal and a reference signal considered to be similar to the desired signal. The results obtained show that particle swarm optimization algorithm has a small mean square error and improved output signal resolution than those of two well known adaptive algorithms namely, Recursive Least Square (RLS) and Sample Matrix Inversion (SMI) algorithms.
