What does the acronym CDMA stand for?

CDMA stands for Code Division Multiple Access, which is a channel access method used by various radio communication technologies. This technique allows multiple transmitters to send information simultaneously over a single communication channel. Each transmitter is assigned a unique code, which enables the receiver to filter out the desired signal from the overlapping transmissions.

CDMA is widely used in mobile communication systems, particularly in 3G technology, as it enhances overall network capacity and efficiency by allowing multiple users to share the same frequency band without interference. The method significantly improves the utilization of available bandwidth, making it a crucial technology in the advancement of wireless communications.

The other acronyms presented in the options do not accurately describe the established telecommunications method known as CDMA. They either reference incorrect terms or do not align with the fundamental principles of how CDMA operates.
