Efficient and low-complexity joint beamforming algorithm for industrial environments: Measurement-based evaluation

In this paper, an efficient and low-complexity joint beamforming algorithm is proposed for industrial environments. In addition, a configuration of a distributed antenna system (DAS) is proposed for a smart factory. The proposed joint beamforming algorithm in conjunction with the proposed configuration is compared with the conventional and state-of-the-art beamforming techniques in industrial communication. Simulation results show that the proposed algorithm outperforms the conventional beamforming algorithms while simplifying the receiver's complexity. The Bit Error Rate (BER) performance of the proposed algorithm demonstrates that good coordination of the interference is achieved leading to highly reliable and more robust wireless communication. The proposed joint beamforming algorithm provides superior performance against the state-of-the-art joint beamforming techniques in industrial environments.
