摘要

Smart antenna system is very useful to increase the capacity, coverage and quality of communication system. Smart antenna combines the antenna array with digital signal processing capability with tracks the mobile user continuously by steering the main beam towards the desired user and at the same time forming null in the direction of interfering signal. This paper presents the performance analysis of Data reusing least mean square (DRLMS) and Least Mean Square (LMS) through beam steering ability and nullifying capability of algorithm and comparative analysis is done using MATLAB 7.14. The simulation result shows that DRLMS has better performance and interference suppression capability, beam steering ability and higher convergence rate than LMS.
