摘要

近年来，电力线通信技术得到了迅速发展。然而，由于电力线信道的不稳定性，在该领域中还存在一些阻塞和衰减问题，降低了该技术的应用前景和范围。本文在对扩频通信和正交频分复用技术进行基础研究的基础上，研究了利用正交频分复用技术抑制低压电力线通信中的阻塞和衰减的方法，并基于电力线的传输特性给出了系统的模型。同时给出了测试和仿真结果，使电力线通信技术更具实用性和应用性。

MATLAB Based Simulation of the Efficiency of the Complex OFDM on Power Line Communication Technology

In the recent years, power line communication technology has seen a rapid development. However, due to the unsteadiness of the power line channels, there are still some problems of obstruction and attenuation in this field which decrease the prospect and scope of this technology. This paper which is based on previous basic studies about spread spectrum communication and OFDM (orthogonal frequency-division multiplexing) investigates the methods of using OFDM to restrain the obstruction and attenuation in low-voltage power line communications and give the systematic model based on the transfer characteristic of power line. Meanwhile the results of testing and simulation are presented which make power line communication technology more practical and applied.
