| Abstract: | Applying coded spread spectrum technique to compressing of frequency-band transmission, the acquisition and tracking theory of coded spread spectrum are analyzed. The problem of actual exercise with the coded spread spectrum technique has been solved by the way of fast acquirement PN. It has been propitious to transmit the anti-jamming secrecy remote-measure image signal in new system. |
