The Implementation of a Dynamic High-performance Notch Filter for Power Line Communications using a WDF Scheme

摘要

PLC (Power Line Communication) technology provides broadband internet access through ordinary power lines. This technology has attracted the attention of operators because the cost required for network configuration is almost zero. The PLC is communication technique transmits voice and data signals through the power lines using high frequencies lying between a dozen kHz and hundreds of MHz. However, the PLC protocol can cause interference with existing wireless communication systems because it uses the same frequency range. Notch filters are a common way to eliminate this interference. In this paper, a dynamic high-performance notch filter incorporating WDF (Ed Note: This acronym should be spelled out at least once.) performance, verified through MatLAB, is presented.
