CDMA is the abbreviation of Code Division MultipleAccess. It is a new and mature wireless communication technology developed on the branch of digital technology, spread spectrum communication technology. The principle of CDMA technology is based on spread spectrum technology, which uses a high-speed pseudo-random code whose bandwidth is much larger than the signal bandwidth to modulate the data which needs to be transmitted, so that the bandwidth of the original data signal can be expanded, and then modulated by carrier wave and sent out.
