Abstract :
In direct sequence (DS) spread spectrum communication system, the first condition of receiving correct data is code synchronization. Synchronization is one of the key techniques in spread spectrum communication systems. This paper presents pseudo-noise (PN) code acquisition and tracking technology. Spread spectrum communication technology is combined with software radio technology to constitute spread spectrum communication system based on software radio technology. Analog circuit design time can be bypassed. And volume, weight and cost of communication equipment are also greatly reduced. Simulation results are given in this paper.
