Code Division Multiple Access

Code Division Multiple Access (CDMA) is 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 mobile phones. Qualcomm pioneered the introduction of CDMA into wireless telephone services.
