1. Apparatus for transmitting a data signal which represents information, said data signal being corrupted by noise which is substantially colored after propagating through a communications medium, said apparatus comprisingmeans for encoding said information using a code, the utilized code providing the encoded information having improved immunity to white noise relative to the uncoded information, andmeans for nonlinearly processing said encoded information in such a manner that distortion associated with subsequent whitening of said noise in receiver apparatus is reduced.
