In this paper the authors consider a real-world set of cables on which Power Line Communication (PLC) signals are transmitted in the power distribution network of a ship. The electrical signals which convey PLC data are carried by unshielded cables and may therefore interact with the external environment and affect the functioning of other devices. On the basis of a set of working assumptions, several...
