With the advent of technology, human dependency on power (electricity) and communication has grown beyond leaps and bounds. Many efforts have been made to continuously improve and increase the efficiency in both areas. Power Line Communication (PLC) is a technology where power lines or transmission lines are being used for communication purposes along with transmitting electrical energy. Because the power grid is already in place, the PLC has the obvious advantage of reducing communication infrastructure cost. However, 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. In order to evaluate the performance of PLC, this paper simulates a practical multipath power line communication channel model and provides the Bit Error Rate (BER) vs signal-to-noise ratio (SNR) curves for orthogonal frequency division multiplexing.
