| 摘 要： | 针对电力线通信中的窄带干扰( NBI,Narrowband Interference),提出了一种基于循环前缀的递推最小二乘(CP-RLS,Cyclic Prefix-recursive Least Square)算法,并将该算法与干扰抑制-正交频分复用(IS-OFDM,Interference Suppressing-orthogonal Frequency Division Multiplexing)技术、循环前缀-分块最小均方算法(CP-BLMS,Cyclic Prefix-block Least Mean Square)以及线性快速分块最小均方(LFBLMS,Linear Fast Block Least Mean Square)算法进行了比较.仿真结果表明,在NBI功率较大时,CP-RLS算法的BER性能与CP-BLMS、LFBLMS算法相比提高了一个数量级,且随着NBI功率进一步增加,其BER性能几乎没有变差；CP-RLS算法更适合信道条件复杂多变的电力线通信.

| Abstract: | A cyclic prefix-recursive least square(CP-RLS) algorithm is proposed according to the narrowband interference(NBI) extensively existing in power-line communication system.A CP-RLS algorithm is proposed and compared with interference suppressing-orthogonal frequency division multiplexing(IS-OFDM) technology,cyclic prefix-block least mean square(CP-BLMS) algorithm and linear fast block least mean square(LFBLMS) algorithm.Simulation results indicate that the proposed CP-RLS algorithm could achieve an-order-of-... |
