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

Abstract: 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 sy… Show more

“…The DE is a simple and effective algorithm that has a small number of adjustable control parameters. It has been successfully used in many engineering applications of several fields such as neural networks, signal processing, pattern recognition, image processing, bioinformatics, control systems, robotics, wireless communications, and semantic web [2][3][4][5][6][7][8]. Exploration and exploitation abilities of any populationbased optimization algorithm play a vital role in enhancing its accuracy and convergence speed [9].…”

“…The SINR maximization is another criterion employed in the joint transmitter and receiver beamforming algorithms [12], [13], [14]. In an analysis of [15], the mixing of differential algorithm based LAA is applied to deepen nulls and lower side lobe levels (SLLs) in the unwanted direction, and they fou-nd the max null depth of -63 dB by using 20 element. The statistic numerical algorithm was proposed to obtain the requirement for the amplitude and phase error of multibeam active phased array antenna [16].…”
