Abstract:

Orthogonal frequency Division Multiplexing (OFDM) has been proposed technique for in-home high speed Power Line Communication (PLC). Several technical challenges are present in using power lines as a networking media for data communication. Power line networking uses power lines existing in homes. The physical topological design of the home wiring poses power line as a networking media. Topological design can be formulated as ‘optimization problem’ and solved by using Simple Genetic Algorithm (GA) and Orthogonal Genetic Algorithm (OGA) technique. OGA is well suitable for it and gives better solution compare to GA. For efficient and reliable communication over power line, a robust physical (PHY) layer is required and which has clear and strong specification for its source and channel coding, modulation and multiplexing techniques. It is satisfied by OFDM technique which carries the signal at a high data rate with few bit errors and suitable for PLC data communication. For topological design, compare to GA, OGA provides best performance. In this paper, OFDM is used as a modulation scheme for PLC and OGA is used to solve the optimized topological design of PLC based on cost constrain.

Keywords: OFDM, PLC, GA, OGA, Physical layer specification, Optimization problem, Topological design, modulation and multiplexing technique.
