         (CDMA) (Or "spread spectrum") A form of
        {multiplexing} where the transmitter encodes the signal using
        a {pseudo-random} sequence which the receiver also knows and
        can use to decode the received signal.  Each different random
        sequence corresponds to a different communication channel.
