摘要
扩频序列的精确同步是接收机正确解扩的关键。文章提出了多符号累加斜率法和变带宽数字延时锁相环两种解决方案 ,实现码片同步。
The accurate synchronization is a key technique for receiver to dispread correctly. The solutions of Multi-symbol accumulation slop technique and a kind of DLL with changeable loop bandwidth is proposed in this paper, to realization of DS chip synchronization .The results of the simulation and practice show the feasibility of the solutions.
