PERFORMANCE OF MAIN BEAM STEERING AT DIFFERENT ANGLE USING GENETIC ALGORITHM

Abstract

The demand for wireless communications constantly grows the need arises for better coverage, improved capacity, and higher transmission quality. Thus, a more efficient use of the radio spectrum is required. Smart antenna systems are capable of efficiently utilizing the radio spectrum and promise an effective solution to the present wireless system problems while achieving reliable and robust high speed high-data-rate transmission. Smart antennas dynamically adapt to changing traffic requirements whose adaptive beam forming approach can be studied with the help of different adaptive algorithms.The fundamental idea behind smart antennas is to improve the performance of the wireless communicationsystem by increasing the gain in a chosen direction. This can be achieved by pointing the main lobes of theantenna-beam patterns towards the desired users. Smart antenna system combines multiple antenna elementswith a signal processing capability to automatically optimize its radiation and/or reception pattern in responseto the signal environment. In this paper we analysis of main beam steering at different angle using genetic algorithm.
