摘要
本文对多路测量信号的扩频通信系统进行了研究,重点分析了接收机同步系统中的捕捉模块和跟踪模块。利用捕捉电路实现粗同步后,再通过跟踪电路使相位完全同步以便于系统解扩恢复原信号。利用FPGA设计了多路测量信号扩频通信的同步系统,并对电路系统进行仿真,其结果满足系统要求。
In this paper spread spectrum communication is studied. Mainly analyzed capturing module,tracking module. Before at-taining the thick synchronization by capture circuit,and then use the tracking module to accomplish complete synchronization. The FPGA design of synchronized technology in the receiver is given and the simulation validation is also carried out.
