摘要：介绍了低压电力线载波通信技术的应用及其关键技术,针对抄表通信系统提出了一种通过降低传输速率的子信道处理方案,发送OFDM符号来换取系统的可靠性。仿真结果表明,在信噪比很低,误码率很高的情况下,系统可以提高通信系统的可靠性。
Introduces the application and key technologies of low-voltage power line carrier-current communication technology.According to AMR Communication system,presents a low-voltage PLC system for AMR based on OFDM,By Reducing transmission rate of child channel scheme and sending OFDM symbol in OFDM system,the reliability of system has been improved.It is proved by simulation that data transmission can be implemented credibly at certain degree under the situation of bad channel and high bit error rate.
