OFDM-IM-AN在电力线信道下的性能分析
Performance Analysis of OFDM-IM-AN Over Power Line Channel
摘要
Abstract
Power line communication is a reliable and effective technology for the power Internet of Things.However,the broadcast nature of power line channels makes them quite easy to be eavesdropped.To protect the security of power line communication,this paper explores an OFDM-IM-AN-PLC scheme based on the evolution of orthogonal frequency division multiplexing(OFDM),specifically OFDM with index modulation(OFDM-IM),in conjunction with artificial noise(AN).The bit error rate(BER)performance and security performance of the proposed scheme are investigated in the cases where both the transmitter and receiver obtain imperfect channel state information(CSI)over the multi-path fading power line channel.Simulation results demonstrate that the OFDM-IM-AN-PLC scheme can provide security for power line communication even when both the transmitter and receiver obtain imperfect CSI.关键词
