Abstract
Smart Antenna technology offers a notably improved solution to reduce interference levels and improve the system capacity. This paper presents an application of QRD based RLS algorithm using Coordinate Rotation by Digital Computer (CORDIC) operator due to its ability to reduce area utilization for implementing smart antenna. The QR decomposition method is used to decompose the co-variance matrix of the RLS algorithm into canonical form to improve the overall beam forming of the smart antenna array. The purpose of matrix decomposition is computational convenience. The designed antenna system has been simulated by using MATLAB and code is generated by using Xilinx (Accel DSP) tool.
