3D Markov Chain Based Narrowband Interference Model for In-Home Broadband Power Line Communication

Broadband power line communication (PLC) is a promising solution for the convergence of Internet, data and video transmissions for in-home networking. Narrowband interference (NBI) is one of the crucial affecting factors of PLC systems and requires accurate modeling. In this paper, the narrowband interference for PLC is investigated using both measurement and modeling approaches. A novel three- dimensional (3D) Markov chain (MC) based statistical model is developed, to model the occurrence of NBI which is associated with the traffic of certain radio users. An intensive performance analysis on the impact of the NBI on PLC is provided. The effectiveness of the proposed model is verified by measured results. The 3D MC model can be used for optimizing future cognitive PLC networks, through simulation-based approaches.
