The Research Of Key Technology Of Parallel Combinatory Spread Spectrum Communication System

The Parallel Combinatory Spread Spectrum Communication System (PC/SS) with the anti-jamming, information transmission with higher efficiency and counter reconnaissance characteristics, is an one of the correspondence methods to have the foreground to develop . Because military correspondence request Concealment with high speed, the adoption of PC/SS system is a good choice.The dissertation use theories analysis ,computer simulation methods with hardware to analyze system performance ,data-mapping method and effect of PN code. Theory analysis and computer simulation show that PC/SS system with larger SNR is viable. If orthogonal spread spectrum sequence is good , PC/SS system performance is excellent for others. PN code's correlation and amount have great effect to PC/SS system .The balance Gold code and chaos sequence based on Logistic-Map are fit to PC/SS system .As for demodulation with many output ,data mapping of self- adaptive PC/SS system is provided by Single Chip Micyoco(SCM) .The balance Gold code and chaos sequence based on Logistic-Map is also provided by SCM . This is an instructive discuss for the key technique of PC/SS system.
