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.

The main changes introduced by HSDPA are new high-speed data channels, the combination of time-division multiplexing with code-division multiplexing, the use of AMC and HARQ techniques, and the relocation of MAC layer scheduling to the Node-B.
The final chapter covers multichannel lightwave systems involving four main techniques for multiplexing, including optical time-division, optical frequency-division, subcarrier and optical code-division multiplexing techniques.
