CDMA

abbreviationStandard termTelecom & IT

A channel access method where multiple transmitters send information simultaneously over a single communication channel.

Code Division Multiple Access is a multiplexing technique where multiple users share the same frequency band at the same time. Instead of dividing the signal by time slots or narrow frequencies, it assigns a unique mathematical code to each transmitter's signal. The receiver uses the same code to extract the desired data from the combined background noise of all other transmissions.
