In this paper, we address the general issue of asynchronous impulsive noise mitigation and its application over coded power-line communications (PLC). As is well known, PLC channels usually suffer from significant degradation due to impulsive interference generated by electrical appliances. The use of a level limiter is a simple and intuitive technique, widely used to mitigate the noxious effect of...
Amplitude clipping is one of the ways to fight against transmission impairments due to impulsive noise. In a recent study, in order to cope with empirical threshold determination, we used a Receiver Operating Characteristic (ROC) analysis to derive a closed form expression of the optimal threshold. In this paper we show that this ROC analysis also corresponds to a maximum likelihood (ML) criterion...
The impulsive noise is one of the main reasons for bit or burst errors in power line transmission. The use of a level limiter is a simple and intuitive technique to mitigate the noxious effect of impulsive noise in such channels. However the appropriate threshold determination remains empirical. In this paper, a suitable calculation of the log-likelihood ratio (LLR) for Turbo codes (TC) in an impulsive...
