摘要
概述了低压电力线统计AR模型的建立方法,并用这种方法得到了实测数据统计结果下的低压电力线信道特性;对LMS和Decision-feedback两种半盲信道估计算法在低压电力线OFDM系统中的性能进行了仿真和分析,二者的性能比较结果表明,LMS算法更适用于低压电力线OFDM通信系统。
The paper discusses the foundation of statistical AR model of low voltage power line firstly, and using this method the statistics measuring data are obtained and the low voltage power line characteristics are showed. The characteristics of the two LMS and Decision-feedback semi-blind channel estimation algorithms used on OFDM low voltage power line system are simulated and analyzed, and the performance comparison result shows that LMS algorithm is more applicable in OFDM low voltage power line system.
