Abstract :
We discuss the transmission over a power line channel that consists of two links. We determine the obtainable rates for time-, and frequency sharing with the “water-filling” argument. Then we show that the two link channel is equivalent to a degraded broadcast channel for which the capacity region is known. Power- and bandwidth constraints determine whether a repeater can improve performance. Another concept from multiuser Information theory, the multi access concept is useful for determining the transmission efficiency from multiple users to a single receiver.
