Description: cdma wireless communication technology in a new and sophisticated digital technology branch- spread-spectrum communication technology developed. The data will be transmitted with a certain signal bandwidth information, bandwidth of the signal with a bandwidth much larger than the high-speed pseudo-random code is modulated, so that the bandwidth of the original data signal to be extended, and then via the carrier modulation and sent. Receiver use exactly the same pseudo-random code, for a correlation processing with the received bandwidth signal, the wideband signal is replaced with the original information data on narrowband signal despreading, in order to achieve information communication.
