Power lines were originally designed for AC power distribution at 50 Hz and 60 Hz, and the characteristics of this channel present some technical challenges for data transmission at these frequencies. This paper presents architecture for the physical layer of a PLC transceiver based on OFDM and the impact of a PLC transmission channel. A suitable and widely accepted PLC channel model is used for simulation purpose. In achieving the aim and objectives of this research work, simulation of PLC system was implemented using OFDM as the choice of modulation scheme. The results obtained compared with the theoretical QPSK result show that OFDM reduced the degrading effect of the PLC channel leading to a good performance. Furthermore, it is observed that at a signal level of 4dB, the simulated BER matches up with the required standard which is the theoretical QPSK value. At this signal level of 4dB,the theoretical and simulated BER graphs converge. Thispoint gives the minimum BER tolerance of 10-2 that is acceptable for data transmission over PLC.
