Impulsive noise on indoor power lines: characterization and mitigation of its effect on PLC systems

Intensive measurements of impulsive noise have been carried out on indoor power lines. From this approach, various types of transients are classified and a stochastic noise model is deduced from the statistical analysis of their main characteristics. A power line communication, based on an OFDM transmission scheme is simulated and, owing to the noise model, different channel coding schemes are tested and optimized to cope with the disturbing effect of this non stationary noise
