ABSTRACT:
A communication apparatus for code-division multiplexing a transmission path includes a spread spectrum transmitter and receiver. The spread spectrum transmitter includes a code-division multiple signal generator, a non-linear code-division multiple signal converter, and a transmitter for transmitting the converted signal. The code-division multiple signal is converted so that the transmitted signal has a plurality of amplitude values. The spread spectrum receiver includes a code-division multiple signal receiver, a non-linear converter for converting an amplitude of the received code-division multiple signal, and a de-spreader for de-spreading the non-linearly converted code-division multiple signal.
