Effect of Noise, Fading and Crosstalk on the BER Performance of a MIMO OF DM Power Line Communication System

摘要

Signal in multiconductor PLC (Powerline Communication) system is affected by fading, noise and crosstalk due to mutual coupling of the conductors. In this paper, a 3x3 MIMO OFDM power line communication system is considered to evaluate the bit error rate (BER) performance following an analytical approach taking into account the total accumulated effect of noise (mainly background noise and impulsive noise), fading, effect of adjacent conductors (crosstalk) and mutual coupling between the conductors of a 3-phase line. The analysis of bit error rate performance is presented numerically. The performance result shows that a 3x3 MIMO PLC system is affected by crosstalk. The analysis is carried out using MatLab simulation. The penalty due to the combined effect mentioned above is approximately 5dB at a bit error rate of 10
