Adaptive Beam Forming Using KLMS, KRLS and CGM Algorithms

In this paper Adaptive beam forming using KLMS, CGM and KRLS algorithm has been proposed. In CGM algorithms has reduced the interference and convergence is better when number of antennas increased. In CGM algorithm the weight of antenna arrays can be adjusted to form certain amount of adaptive beam to track corresponding users automatically and at the same time to minimize interference arising from other users by introducing nulls in their directions. The experimental results show that the different algorithms of array factors, mean square error and performance of different antennas on each algorithm. The CGM algorithm has better convergence, low computational complexity and minimizing interference compare to other algorithms.
