Impulsive Noise Modeling and Mitigation Toolbox
Powerline distribution networks are increasingly being employed to
support smart grid communication infrastructure and in-home LAN
However, their primary function of power distribution results in a
hostile environment for communication systems.
In particular, asynchronous impulsive noise, with levels as high as
50 dB above thermal noise, causes significant degradation in
Much of the prior work uses limited empirical measurements to propose
a statistical model for instantaneous statistics of asynchronous noise.
In this paper, we
The results of this paper can be used to analyze, simulate, and
mitigate the effect of the asynchronous noise on PLC systems.
- derive a canonical statistical-physical model of the instantaneous
statistics of asynchronous noise based on the physical properties
of the PLC network, and
- validate the distribution using simulated and measured PLC noise data.
