Performances of RLS algorithm for smart antennas in mobile communication system

The smart antennas are widely used for wireless communication because it has an ability to increase the coverage capacity of a communication system. The main purpose of the smart antenna system is the selection of smart algorithms for adaptive array. On this paper, one of the adaptive beam forming approach used in smart antennas called Recursive Least Square Algorithm (RLS) is presented. The efficiency of RLS algorithm is compared on the basis of normalized array factor and mean square error (MSE) for mobile communication. The performance of RLS algorithm is analyzed by using MATLAB software and all the simulated results are presented on this paper.
