Abstract:
1. A method for communicating information over a conductive path, comprising: encoding a first information set in a first signal and encoding a second information set in a second signal, wherein the first signal and the second signal are electrical signals and the power spectrum of the first signal overlaps the power spectrum of the second signal; transmitting the first signal onto the conductive path at a first point, and transmitting the second signal onto the conductive path at a second point, wherein the first signal is transmitted during a first set of time intervals, the second signal is transmitted during a second set of time intervals, and the first set and the second set of time intervals are substantially non-overlapping; receiving the first signal at a third point on the path and recovering substantially all of the first information set from the first signal received at the third point; and receiving the second signal at the third point and recovering substantially all of the second information set from the second signal received at the third point, wherein the first, second, and third points are at different locations on the conductive path.
