Real time beamforming algorithms: Experimental validation

Abstract

In this paper, a custom software defined radio that implements a smart antenna array is used in the task of real-time beamforming. Specific beamforming algorithms are implemented in FPGA, remotely controlled by a computer host. The antenna array is mounted in a metallic cylinder and tested in anechoic chamber. Experimental measurements highlight the efficiency of the algorithms implementation. Moreover, the performance differences between the algorithms allow a better comprehension of the challenges of such real-time implementation regarding the hardware, software, and firmware developments.
