摘要
对CDMA下行信道和上行信道进行干扰,实现干扰CDMA系统的目的。重点分析了对CDMA下行信道的干扰方法和对CDMA上行信道的干扰方法,包括对下行信道的非相干压制式干扰、对下行公共信道的相干伪码扩频干扰和基于伪基站的欺骗式干扰,以及对上行信道非相干式压制式干扰和对接入信道的欺骗式干扰,归纳得到各种干扰方法的原理、优缺点、对侦察的需求及其适用范围。
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
