摘要
论述了GPS(全球定位系统)软件接收机相关原理,并基于MATLAB软件实现了GPS接收处理模块的软件仿真。该仿真系统可实现GPS信号的捕获、跟踪和解调定位处理。在给出所模拟的信号输入后,结果表明该模型的设计正确可行。使用该系统可为进一步研究各种算法提供一个方便快捷的仿真平台。
GPS has been broadly applied in every field of our social life. The research of GPS gains more and more attention. GPS software receiver had great advantages in reconfiguration and flexibility. This paper presents the simulated model of the GPS signal processing module based on MATLAB software tools. This model can perform the acquisition, tracking, and modulations of the GPS signal. The processing results are given out as the simulated GPS source input. The result indicates this model is correct and feasible. This module can provide the research platform for various kinds of design and assessment of new signal processing methods.
