摘要

针对目前低压电力线通信技术的传输复杂性及外部噪声失真等问题，本文基于正交频分复用（Orthogonal Frequency Division Multiplexing，OFDM）调制技术模型，建立了低压电力线信道的通信传输模型，并在MATLAB软件中仿真研究了低压电力线通信系统的传输特性及抗噪声效果。研究结果表明，OFDM技术能够有效提升低压电力线通信系统的传输性能，并显著降低通信系统的噪声影响。该技术具有较好的市场应用前景及竞争力。

Abstract

Aiming at the problems of transmission complexity and external noise distortion of low-voltage power line communication technology

based on the orthogonal frequency division multiplexing (OFDM) modulation technology model

the transmission model of low-voltage power line channel is established. The low-voltage power line communication system is simulated and studied in MATLAB software. The results show that OFDM can effectively improve the performance of low-voltage power line communication system and significantly reduce the noise impact of communication system. The technology has good market application prospects and competitiveness.
