What is scrambling codes?

Scrambling codes are unique sequences used in communication systems, particularly in CDMA (Code Division Multiple Access) networks, to differentiate between multiple users accessing the same frequency channel. They help to spread the signal across a wider bandwidth and mitigate interference by effectively randomizing the data before transmission. This ensures that the receiver can accurately decode the intended signal while filtering out noise and other users' signals. Scrambling codes enhance system capacity and improve the overall quality of communication.
