5G Relay Coverage Enhancement Technology for Underground Power Monitoring

By deploying and using multi-hop transmission of multiple relay nodes to achieve relay coverage enhancement, 5G network can effectively solve problems such as weak coverage and blind coverage of underground power pipeline corridors. This paper mainly studies the 5G relay coverage enhancement technology for underground power monitoring. In this paper, the decoding performance of the relay node is analyzed, and the interrupt probability of the system and the progressive performance trend of the system under high signal-to-noise ratio (SNR) are derived, namely diversity gain and error flat layer. It can be seen from the experimental results that with the increase of \(\mu\) , the optimal relay working in full-duplex mode can eliminate more self-interference, and the residual self-interference is smaller, which has less impact on the system performance, and better relay coverage enhancement technology can be obtained.
