Performance Analysis of Existing Beam forming Methods for Various Antenna Elements and Interference Sources
Main Article Content
Abstract
Antenna arrays make use of techniques like Maximal Ratio Combining or Diversity Combining to achieve a high Signal-to-Noise Ratio (SNR). The two major algorithms used are Direction of Arrival (DOA) and Beamforming. This paper studies and performs a performance analysis of existing beamforming algorithms, namely, Least Mean Square (LMS), Recursive Least Mean Square (RLS), Griffiths, and Variable Step Size Griffiths (VSSG). The algorithms are simulated for various cases, including Low RF Sources and Single Interference, Large RF Source and Single Interference, Low RF Sources and Multiple Interference angles, and finally, in the case of Large RF Sources and Multiple Interference angles.
