In mobile communication systems, capacity and performance of network are usually limited by two major impairments. They are multipath and co-channel interference. Smart antenna is one of the most promising technologies that will enable a higher capacity in wireless networks by effectively reducing multipath and co-channel interference Smart Antenna use adaptive beam forming algorithms in a dynamic environment continuously adjusting the weight of antenna arrays for creating a beam to track desired users automatically, and minimize interference from other users by placing nulls in their directions. This paper provides comparative analysis to results of LMS and SMI adaptive algorithms for one desired angle and three undesired angles using MATLAB software Results of simulation will help in beam forming and antenna design.
