基于DSP的GPS软件接收机设计
摘要
本文研究了一种基于软件无线电思想的全球定位系统(GPS)软件接收机的实现,重点在于其实现的整个过程都放在数字信号处理器(DSP)内采用全软件的方法来完成,从而有效地节省了硬件资源和成本,并且更加方便和灵活。
在本文的主体部分阐述了GPS信号的特点,数字相关器的结构和工作原理,并且详细介绍了搜索,捕获和跟踪GPS信号的原理,最后给出了实现基于DSP的软件接收机的各个模块的软件流程图。
文章阐述了一种GPS软件接收机的实现方法,软件GPS接收机具有多种用途,既有军事应用也有商业应用,有很好的发展前景。
This dissertation researches a realization method of Global Position System(GPS) receiver based on software radio theory. The emphasis of this research is that overall the receiver is realized in digital signal processor (DSP) by pure software method that can efficiently save hardware resource and cost and carry out easier and more flexibly.
In the main body of this dissertation,we expatiate on the characteristic of GPS signal,the structure and work principle of digital correlator and introduce how to search ,capture and track the GPS signal in detail.At last,we give the software flow chat of each module about the GPS software receiver based on DSP.
This dissertation expatiates a realization method of GPS software receiver.Software receiver has various uses in military application as well as commerce,and has good developing expectation.
