Adaptive Beamforming using CMA

Smart antenna possess the capability of suppressing jamming signal, so they can improve signal to interference plus noise ratio (SINR). Smart antenna is most efficient leading innovation for maximum capacity and improved the quality and coverage. Smart antenna radiates not only narrow beam towards the desired users exploiting signal processing capability but also place nulls towards interferes thus optimizing signal quality and enhance capacity. In this paper Constant Modulus Algorithm(CMA)algorithm used for adaptive beamforming is presented. CMA in adaptive beam forming minimizes MSE. Therefore CMA is found more efficient algorithm to implement communication environment to enhance service quality and capacity.
