Performance Analysis of Differential Evolution Algorithm based Beamforming for Smart Antenna Systems

By Amara Prakasa Rao N.V.S.N.Sarma

This paper presents smart antenna array beamforming using differential evolution algorithm. The excitation values of the elements in the array are smartly adjusted to control side lobe levels and placing nulls in the interference signal direction while maintaining the beam in the desired signal direction. Different cases are considered to illustrate the performance of this technique. Simulation results show that this evolution algorithm is better than the traditional beamforming algorithms for Smart antenna systems.
