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.
