摘要:

正交频分复用 (orthogonal frequency division multiplexing,OFDM)技术与跳频(frequency hopping,FH)技术结合能显著提高系统容量与传输速率,并具有抗多径衰落与抗干扰能力, 非常适合于在电力线上实现高速数据通信。在分析了低压电力线信道特性的基础上,提出了基于FH-OFDM的电力线通信的总体设计方案,利用MATLAB建立了系统的仿真模型。通过仿真,证明了FH-OFDM系统比传统OFDM系统、跳频系统具有更好的误码率性能。

Abstract:

The orthogonal frequency division multiplexing(OFDM), technology combining with frequency hopping(FH) technology will increase system capacity, improve transmission rate, and effectively resist multi-path fading and interference. Therefore, FH-OFDM technology is applicable in high speed communication of the power line. Based on the characteristics analysis of low voltage power line channel, the design scheme of a FH-OFDM system is presented. The system is simulated by MATLAB. It is shown that the bit error rate(BER) performance of the FH-OFDM system is better than that of the traditional OFDM and FH system.
