Selected Coding and Modulation Techniques for Reliable Power Line Communications

Power line communication is a technology that can use available power line for communication. The key advantage of power lines is that they provide a ‘pre-installed’ infrastructure of wires and wall outlets that are easy to access throughout a building. On other hand there are many challenges in using this medium for high-speed communication. In this paper A model of power line grid in a low voltage network has been configured, PLC characteristics have been studied according to previous works, noises model and PLC model have been simulated using MATLAB™/SIMULINK with the use of different modulation and coding techniques fit for the low-voltage PLC Utilities.
