波束成形技术在无线互联电力仪表抗干扰中的应用
Application of beamforming technology in anti-interference for wireless interconnection electric meters
摘要
Abstract
The wireless interconnection of electric meters has brought great convenience to the users,but it faces with the anti⁃interference problem of wireless communication in complex electromagnetic environment. The complexity of the electromag⁃netic environment is analyzed,in which the received signal and interference of each communication node are generally polydirec⁃tional,and the direction of arrival(DOA)is uncertain. The interference simulation model of DC motor was established. The in⁃terference suppression method based on beamforming technology is proposed,in which the DOA of interference wave is estimated by MUSIC algorithm,and then the beamforming is calculated based on LCMV algorithm. The simulation results indicate this method can restrain the interference effectively,and improve the bit error rate(BER)of communication link significantly.关键词
