Performance Evaluation of Non–Coherent Transmission over Power Lines

High–bit–rate communication over power lines is a promising solution to the last–mile problem. We examine the use of bandwidth–efficient, non–coherent multicarrier modulation as simple, flexible, and robust transmission scheme over power–line channels. Adaptive, requiring channel state information at the transmitter, and non–adaptive multicarrier modulation are discussed and assessed. The effects of moderate complex channel coding on both modulation schemes are pointed out by simulations.
