Performance Analysis of Adaptive Beamforming Algorithms

Abstract

Adaptive Antenna System consists of Beamforming techniques in which the beam generated in the direction of desired signal and nulls are placed in the direction of undesired signal (interference). The analysis of two such algorithms - Least Mean Square and Normalized Least Mean Square Algorithms are discussed in this paper. These algorithms have the ability to change the amplitude and phase values that are passed to the individual elements in the Antenna Array. The simulation results suggest that the Normalized Least Mean Square Algorithm converges much faster than the Least Mean Square Algorithm. The Adaptive Beamforming Algorithms are simulated and verified using Matlab software.
