| 摘 要： | 为了更好地以电力线为传输媒介进行数据传送和信息交换，对电力线通信系统发射接收机原理结构进行了研究．在设计了帧前导和帧控制符号的基础上，使用Matlab、C语言建立了与Homeplug AV协议相兼容的基于OFDM的电力线通信仿真系统，在协议基础上对系统性能和系统实现的关键技术进行了数据仿真和分析，并进行了低压电力线通信信道建模．结果表明，仿真系统的数据传输速率可达100Mbit／s以上．当信噪比达到7dB左右时，系统误比特率已降到10^-6数量级，基本实现了高速、可靠的电力线通信．

| Abstract: | In order to transmit data and exchange information via power line channel, the principle and structure of transceiver for power line communication were studied. After the preamble and frame control being designed, simulation of power line communication system based on OFI）M that is compatible with HomePlug AV standard was built with Matlab and C language. According to the protocol, the performance and key techniques of the system were simulated and analyzed. The channel of low power line communication was also modeled. The result indicates that the transmission rate of simulation system may exceed 100 Mb/s. With the SNR of 7 dB, the bit error rate decreases to 10^-6 level. High speed and reliable power line communication can be realized. |
