摘要
将220 V低压电力线作为互联网通信的信道是现在研究的热题,但是由于低压电力线的信道特性使得通信质量会不太理想。基于这一实际问题,本文提出了一种新的改进式变步长均衡算法。该算法实时性高,信道均衡性能良好,仿真实验证明,新算法收敛速度较快,均方误差的稳态值较小,跟踪速度较快,并且运算简单,有效提高了低压电力线信道互联网通信性能。
The 220 V low-voltage power line as the channel for Internet communication is a hot topic for research,but the communication quality will be less than ideal due to the channel characteristics of the low-voltage power line.Based on this practical problem,the paper proposes a new improved variable step size equalization algorithm.The algorithm has high real-time performance and good channel equalization performance.The simulation experiment proves that the new algorithm has faster convergence speed,the steady-state value of the mean square error is smaller,the tracking speed is faster,and the operation is simple,which effectively improves the performance of low-voltage power line channel Internet communication.
