摘　　要：采用电力线作为信息传输的媒介时,其信道环境存在复杂性和多变性,使之具有诸多技术难点,特别是在低压线路上,需要采用多载波调制和解调技术实现。应用MATLAB/SIMULINK软件搭建滤波多音调制系统的仿真模型,实现该系统的调制与解调过程。在仿真过程中对3种原型滤波器以及3种均衡器进行了性能比较。仿真结果表明:滤波多音调制技术在低压电力线载波通信中应用是可行的,并可以提高其通信质量。As a medium of information transmission, there are complexity and variability in the channel environment of power line. Many technical difficulties are to overcome especially in the low-voltage power line. The multi-carrier modulation and demodulation techniques should be use. In this paper, MATLAB / SIMULINK software were used to build a simulation model for FMT system and completed the modulation and demodulation of this system. And during the simulation, it was finished that the performance comparison of three prototype filters and three equalizers. The simulation results and the use of the achievable bit rate showed that the feasibility of application of the filtered muhitone in the low-voltage power line cartier communication and its quality couht be improved.
