Code Division Multiple Access

communications (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.
