How to deal with impulsive noise in OFDM-based PLC: A survey

Power-line communications (PLC) is a favorable technology for smart grid systems due to the wide penetration of power-line infrastructure. Broadband PLC (BB-PLC) is required for future smart grid applications as the data traffic may be high. However, BB-PLC performance is degraded by the occurrence of impulsive noise. Some methods have been proposed to reduce the effect of the impulsive noise in BB-PLC. In the liteature, the classification of impulsive noise mitigation methods has not been available. In this paper, we aim to develop a classification of the impulsive mitigation methods and provide a brief discussion of each method. The classification is useful as a further reference of designing BB-PLC systems under impulsive noise environment.
