Power Line Noise Models and Energy Detection in the High Frequency Radio Band

摘要

Electromagnetic interference from power lines is one of the main sources of man-made interference to communications in the high frequency (HF) radio band. Two types of radio interference generated by power lines are gap-type noise caused by electric discharges across line hardware and corona noise caused by the partial breakdown of the air due to the high electric fields around transmission line conductors. Using original data, this research has developed a parameter based model of gap-type and corona noise, that allows the fundamental noise mechanisms to be mechanically or physically simulated. An expression for the power spectral density (PSD) of gap-type noise and corona is derived.
