An Adaptive Beamforming Algorithm based on FPGA synthesis for MIMO Antennas

The Multiple Input and Multiple Output (MIMO) system, combined with adaptive beamforming antenna array technology, is prospective to play a significant role in the 5G wireless system. The objective of the beamforming technique is to steer the beam in the necessary direction and to reduce interference in the other direction using an adaptive filter. This paper aims to incorporate the antenna array system into the hardware. Therefore, the adaptive beamforming algorithm is designed, developed and synthesised using Verilog (VHDL) with the Electronic System Level (ESL) System Vue software and ModelSim tool. In this paper, with the help of ESL System Vue software, the intended signal and interfering signals are generated for the Millimeter (mm)-wave frequency, with 8 uniform linear array antennas. These signals are fed to the hardware architecture of the beamforming algorithm. From the result, it is detected that the proposed adaptive beamforming algorithm has better performance when related to the other algorithms.
