Code Division Multiple Access (communications) (CDMA) (Or "spread spectrum") A form of multiplexing where the transmitter encodes the signal using a pseudorandom 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. Last updated: 2001-03-28
