Low cost smart antenna array hardware implementation

Abstract

This paper presents and describes a low-cost hardware implementation of smart antenna based on FPGA. Unlike systems using high-cost devices, the case herein uses a low-end FPGA for beamforming algorithm implementation, enabling smart antenna applications in practical and commercial problems, as for instance interference mitigation. The low-cost smart antenna array underwent two different types of tests, solving the beamforming problem by a non-adaptive algorithm and by a blind adaptive one. The desired beamforming is reached in both cases and interference mitigation is achieved in the second one.
