Development of Low Cost Smart Antenna System and its FPGA Implementation

Harshveer Singh Grewal | Paramveer Singh Gill

Abstract: Recently, smart antennas have been proposed as a promising solution that can significantly improve the quality of wireless transmission, which is limited by interference, local scattering, and multipath propagation. The antenna array is combined with digital signal processing to give a narrow beam pattern in response to the received signal by the smart antenna. The weights of the beam-former is calculated by using the adaptive approach which uses reference signal and the direction of the user based on the received signal. The main beam is then directed towards the specific user, while the nulls are adjusted toward the interferers [1]. This paper presents the development of a smart antenna using QD (Quadratic Decomposition) RLS algorithm and its FPGA implementation. FPGA resource estimates and the implementation results have been presented in this paper.
