A brief analysis of mobile communication jamming

CDMA networks, because the system uses Code division multiple access technology, all users use the same frequency band, mutual use of unrelated PN code as a spread code to differentiate, because of this feature, the existence of the same frequency interference is inevitable; at the same time, the amount of interference depends on the number of telephone users, the system capacity also changes (that is, soft capacity). From the subjective aspect, the
