(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. Motorola uses CDMA for digital cellular phones. Qualcomm pioneered the iNTroduction of CDMA iNTo wireless telephone services. (2001-03-28)
