| 摘 要： | 为了在恶劣复杂的电力线多径信道上传输高速的数字信号,该文提出了一种新的电力线通信(PLC)方式--基于THP预编码的单载波正交振幅调制(QAM)方案.该方案使用THP预编码来均衡信道从而达到去除码间干扰的目的,实现最大可能的利用电力线信道资源.计算机仿真实验和实际测试表明:单载波QAM能够在短距离内实现在电力线上传输高速数据,并且具有很好的比特误码率性能.

| Abstract: | In order to transmit high speed data in powerline communication multipath channels,a new method is proposed.The method is based on the THP precoder and single carrier quadrature amplitude modulation.It uses the THP precoder to get rid of the interference between codes.It can make full use of the channel resource of powerline communication(PLC).The computer simulation and the actual test show that: this method can complete transmitting high speed data in PLC channel,and it has good bit error rate performance... |
