毫米波通信系统中基于GPS的时统设计
|
摘要
随着全球定位系统(GPS)在全球的快速发展,特别是在通信系统中的使用,使得对GPS授时的要求越来越高。本文所设计的GPS时统电路是毫米波跳频通信系统中的重要组成部分,论文对GPS时统所涉及到的关键算法和软、硬件实现进行了设计,主要内容有以下几个方面:
1.以DSP为主处理芯片,完成了GPS接收模块的硬件设计,着重设计了DSP部分的硬件电路,包括时钟芯片接口电路设计、串口模块设计、电源部分设计。
2.在分析DSP应用软件开发方法和GPS导航电文的基础上,完成了GPS时间码的算法、微秒数量级时钟芯片驱动、中断服务子程序等软件的编写,并用DSP对微秒数量级时钟芯片进行时间细分、输出细分后的时间脉冲,保证了跳频通信的时间精度。
With the rapid application of Global Positioning System in the world, especially in the field of communications, the timing system of GPS is required to be more and more accurate. The electro circuit on GPS command-and-control system of time synchronization, which plays an important role in Millimeter Wave (MMW) Spring Frequency Communications, has been designed in this thesis. In addition, the key algorithm for the synchronization of GPS signals, the crucial hardware and software to conduct the calculation has been devised. The main points are as follows:
1. DSP is applied to process the chips, and the hardware of GPS receiver module is devised. Besides, Efforts has been put to the design of DSP hardware circuits, including the interface circuit to Synchronization Clock Chip, Serial interface module circuit, and the power supply device.
2. Based on the analysis of the application of DSP technique on the software developing methods and GPS navigation text of a telegram, the calculation of time, driving of microsecond-scale clock chip, and programming of interrupting the sub-program service are fulfilled. By means of subdividing time of the microsecond-scale chip, and outputting the subdivided time pulse, time precision of the spring frequency in communications has been guaranteed by applying DSP.
