Study of Computer in Smart Antenna System: A Comprehensive Approach

In the recent years, advancement in telecommunication technologies and the increasing demand of data rate has motivated the optimized use of frequency spectrum. One technique for the efficient usage of frequency is Smart Antenna system. In this work, the proposed novel least mean square algorithm (No-LMS) build and studied the results as comparative work with results of two another algorithms called Standard LMS algorithm(S-LMS), and normalized LMS algorithm (N-LMS). The computer simulation work results based No-LMS algorithm have better performance refer to obtain the optimum convergence factor (CF)and shows that robustness smart system, good tracking capability, and high adaptation accuracy than the other algorithms. The smart antenna system that is based on LMS-algorithms for all types (S-LMS),(N-LMS),and(No-LMS) show that this system is affected by the convergence factor, the computer simulation results shows the minimum mean square error (MSE = 0.007) is obtained for the value of convergence factor equal to (0.2). The test of the three algorithms for different values of signal to noise ratio (SNR) show that the(No-LMS) algorithm gives the minimum MSE values compared with the two those obtain from other algorithms.
