Received noise on powerline communications where the in-building wiring acts as an antenna

摘要

The powerline channel is considered as a challenging channel due to the heavy load and noise impairments. In this paper we investigate an important type of measurement with regards to the powerline communications channel, where the low voltage wiring inside a house is considered as a receiving antenna for interference. Several types of measurements are presented using the corresponding broadband PLC channel as a communication medium. Impulsive and interference noise play a major role in the contamination factors on a powerline channel. The results include the different measurements of noise in the frequency domain. Extensive tests and measurements have been used to ascertain which specific external interference, after filtering by the coupling circuit, does affect the entire PLC system being used in a house.
