Performance Analysis of Smart Antenna Beam forming Techniques

چکیده
The wireless cellular base station antenna system employs switched beam technology which suffers from its inefficiency to track the user and limited capacity. The Smart antenna tracks the mobile user more efficiently by directing the main beam towards the user and forming nulls in the directions of the interfering signal. Smart antennas include the design of antenna array and adjusting the incoming signal by changing the weights of the amplitude and phase using efficient DSP algorithms [1]. This paper mainly focuses on the adaptive beam forming algorithms such as LMS, SMI, RLS, CGA, CMA and LSCMA applied for uniform linear array antenna. The above adaptive algorithms are simulated using MATLAB. Results obtained are then compared.
