Abstract
An Apparatus for extracting communications signals from power lines, which lines are arranged such that leakage of signals occurs between them. The apparatus receives a signal from each of at least two of lines (blue, red, yellow) and combines the received signals so as to increase the ratio of wanted signal to interference plus noise S/(1+N). Preferably the combining is achieved by weights W.sub.B, W.sub.R, W.sub.Y and a summer. The weights phase shift and scale the received signals in amplitude. The apparatus can also be used for transmitting in the downstream direction.
