Impulsive noise remains one of the important issues for data transmission over power lines. Many studies show that, compared to the single carrier modulation scheme, the OFDM not only fights against the channel time dispersion, but also helps to mitigate the noxious effects of such kind of noise. The OFDM/OQAM is an alternative multicarrier scheme that exhibits a higher theoretical spectral efficiency...
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...
