Analysis of the optimal jamming method to direct sequence spread spectrum communication systems

This paper elaborates the basic principle of direct sequence spread spectrum communication, analyzes and compares the efficiency of typical jamming methods such as aimed jamming and barrage jamming to direct spread spectrum communication system, and carries out corresponding simulation using Simulink platform. It is concluded finally that the optimal jamming method is the barrage jamming with the optimal jamming bandwidth, which is of guiding significance for direct sequence spread spectrum communication without narrowband suppression technology in practical communication confrontation.
