Analysis on Jamming Methods on CDMA System

By jamming the downlink channel and uplink channel of CDMA system,the purpose of jamming CDMA system is achieved.After simple analysis of downlink channel and uplink channel,the main jamming ways are focused against CDMA communication,including the analysis of the jamming against downlink channel and uplink channel of CDMA,such as non-coherent suppression jamming against downlink channel,coherent pseudo-code spread spectrum jamming on the downstream public channel and deception jamming based on pseudo base station,non-coherent blanket jamming and deception jamming to CDMA access channel.The principle,the advantages and disadvantages,the requirement of reconnaissance and application scope of each jamming way are proposed.
