Code Division Multiplexing
Code Division Multiplexing (CDM) is a communication technique that allows multiple signals to share the same transmission medium simultaneously. Each signal is assigned a unique code, which allows it to be distinguished from others. When signals are sent, they spread over a wide frequency range, making it possible for the receiver to filter out and decode the desired message using the specific code. This technology is commonly used in mobile phone networks, improving capacity and reducing interference, enabling many users to communicate at the same time without disrupting each other.
