TLDR
In this article, a mathematical model that allows the fundamental mechanisms of gap-type noise to be simulated is presented, which can be used to derive an expression for the demodulated power spectral density (PSD) compared with field observations.Abstract:
Electromagnetic disturbance from power lines is one of the main sources of man-made noise affecting communications in the high-frequency radio band. Most radio disturbances generated by power lines are of two types: 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. While the physical mechanisms of these noise types have been investigated in detail, these studies have not yet been used to develop noise models for the evaluation of communication-system performance. This paper presents a mathematical model that allows the fundamental mechanisms of gap-type noise to be simulated. With this model, the effect of gap-type noise processes on various high-frequency communication systems can be determined by direct computation as well as by experimental observation. The mathematical model was used to derive an expression for the demodulated power spectral density (PSD) compared with field observations.read more

A Model of Electromagnetic Interferences Induced by Corona Discharges for Wireless Channels in Substation Environments
TL;DR: In this article, a generalized model of impulsive electromagnetic interference induced by corona discharges for wireless channels is proposed. But the model does not take into account the physical mechanism of these discharges and the induced electromagnetic radiations.

Amplitude-probability distribution of atmospheric radio noise
TL;DR: In this paper, the amplitude distribution of atmospheric noise is derived, and it is well approximated by the distribution of the sum of a Rayleigh vector and a vector with lognormally distributed amplitude.
