N2 - Direct sequence spread spectrum technology is applied widely in wireless communication because of its merits, such as anti-interference ability, good concealment, and being easy to realize Code Division Multiple Access. A Direct sequence spread spectrum communication system based on DSP is designed in the paper, including baseband processor, intermediate frequency modulator/ demodulator, local oscillator, up/down converter, keyboard, LCD monitor and DSP controller, etc. The experiment results of transmission shows that the direct sequence spread spectrum system designed can obtain spectrum after IF modulation with 40dBm peak level and 20MHz bandwidth in 4dBm level to meets system requirements. And it can realize effective data transmission and anti-interference communication with advantages of higher data transmission rate and wider spectrum range than the traditional circuits.
