Abstract
A method and apparatus for immediately identifying the presence and the source of interference in a communications system. A separate identification code is superimposed on each signal transmitted from a separate transmitter. At any receiver, if an undesired signal causes interference, it can be idenified via its associated identification code. In one embodiment, spread spectrum chip sequences are used as the identification codes.
