Abstract: Power line communication (PLC) approach is in demand owing to its high data rate and low cost. PLC has a number of application areas ranging from home automation to internet access. Since the power grid is designed optimally for power delivery (not the data), the power transmission line generally appears as a harsh environment for the low-power high-frequency communication signals. The electrical appliances in the power-line network produce different types of noises, leading to performance degradation. In this paper, an algorithm is used to detect the presence of periodic impulsive noise in the orthogonal frequency division multiplexing (OFDM) based PLC system and then suppress it with an adaptive infinite impulse response (IIR) notch filter. The simulation results show that the periodic impulsive noise mitigation technique is simple and effective for the OFDM- based PLC system.
