In this work the effects of impulsive noise from number of home electrical appliances in power line medium is investigated. This is an extension to a paper already published in ISPLC 2011 [1]. The analysis in this work focuses on the properties of impulse noise in frequency range of 100MHz – 200MHz and compares the effect of noise with the lower frequency bands.

Proposed is a new subband adaptive filter (SAF) algorithm by minimizing Huber’s cost function that is robust to impulsive noises. Generally, this algorithm works in the mode of the normalized SAF (NSAF) algorithm, while it behaves like the sign SAF (SSAF) algorithm only when the impulsive noises appear. To further improve the robustness of this algorithm against impulsive noises, the subband cu...

Noise control of signals is a key challenge problem in signal enhancement, signal recognition, communication, radar, and sonar applications. The most widely used method is adaptive linear filtering method, which can adaptive change filter parameters with the stochastic property of the stationary Gaussian noise. The representative algorithms of this include least mean square (LMS) adaptive filte...
