摘要
介绍了低压电力线用于数据传输的接入方式和信道特性,在分析了正交频分复用OFDM原理的基础上,提出采用Altera公司的APEX20K系列可编程逻辑器件PLD的OFDM基带硬件解决方案,并用matlab模拟信道特性对结果进行了分析。
This paper first introduces access pattern and channel characteristics of low voltage power line, and then presents the hardware implementation scheme using APEX20K family PLD(programmable Logic Device) on the basis of describing the basic principle of OFDM(Orthogonal Frequency Division Multiplexing ) modulation,and finally analyzes the results by matlab.
