摘要

本文提出了一种用于窄带(9khz -490 kHz) PLC系统脉冲降噪的最佳裁剪/消隐非线性技术。该优化技术基于最小误码率(BER)搜索。在我们的仿真中，我们使用常见的自下而上方法和散射矩阵方法推导了典型低压(LV) PLC网络的传递函数。在误码率与信噪比(SNR)方面的仿真结果表明，提出的技术提高了窄带PLC系统的误码率性能。

Impulsive noise reduction of a narrowband power line communication using optimal nonlinearity technique

In this paper, we propose an optimal Clipping/Blanking nonlinearity technique for impulsive noise reduction in narrowband (9 kHz-490 kHz) PLC system. This optimal technique is based on the minimum bit error rate (BER) search. For our simulation, we have derived the transfer function of a typical low voltage (LV) PLC network using the common bottom-up approach and scattering matrix method. Our simulation results, in terms of BER versus signal to noise ratio (SNR), show that the proposed technique improves the BER performance of the narrowband PLC system.
