摘要

针对中压电力载波通信中由电力线信道的复杂特性和动态噪声环境导致的数据传输效率低下、抗干扰能力弱以及信号传输可靠性差的难题，将数字信号处理（digital signal processing，DSP）作为中压电力载波通信系统的核心控制单元，结合正交频分复用（orthogonal frequency division multiplexing，OFDM）模块和长短期记忆（long short-term memory，LSTM）网络信道噪声模型设计，实现了一种高度集成且智能化的通信技术系统。该系统能够根据电力线信道的复杂特性和动态变化的噪声环境，通过合理分配子载波资源、高效调制解调和实时噪声预测与抑制，显著提高通信系统的频谱效率、抗干扰能力和信号传输的可靠性。实验结果表明，该设计的平均绝对百分比误差（mean absolute percentage error，MAPE）仅为10.62%，均方根误差（root mean square error，RMSE）仅为7.20%。所提系统为中压电力载波通信提供了一种高效、精确的解决方案，有助于推动智能电网、远程监控等领域的进一步发展。

Abstract

Addressing the challenges of low data transmission efficiency

weak interference resistance

and poor signal transmission reliability in medium-voltage power line carrier communication due to the complex characteristics of power line channels and dynamic noise environments

a digital signal processing (DSP) as the core control unit of the medium-voltage power line carrier communication system was proposed. By integrating orthogonal frequency division multiplexing (OFDM) modules and an long short-term memory (LSTM) channel noise model

an advanced

highly integrated

and intelligent communication technology system has been developed. This system adaptively allocates subcarrier resources

employs efficient modulation and demodulation techniques

and performs real-time noise prediction and suppression

significantly enhancing the spectral efficiency

interference resistance

and reliability of signal transmission in the communication system. Experimental results demonstrate that the proposed design achieves a mean absolute percentage error (MAPE) of only 10.62% and a root mean square error (RMSE) of merely 7.2%. This innovative technological system offers an efficient and precise solution for medium-voltage power line carrier communication

facilitating further advancements in smart grid and remote monitoring fields.
