WIDE BAND TRANSMISSION THROUGH WIRE

摘要

A method for broadband transmissions through metallic wire in an interferenc e- laden environment. Wideband communication through a wire is achieved in the presence of other wideband signals in the wire or in adjacent wires by applying a modulation schema to the wideband communication signal that forms a signal which is orthogonal or nearly orthogonal to all other signals that ar e present in the wire, whether directly applied or electromagnetically induced . In accordance with one illustrated embodiment, a CDMA code is applied to the wideband signal that is to be communicated through a given wire, and the cod e that is employed is orthogonal to the CDMA codes that are applied to other signals that flow through the wire or through other wires which are in the neighborhood of the given wire.
