摘要
导航电文的生成以及帧同步验证是研制短波无线定位中信号模拟器的重要部分,获得正确的导航电文信息和帧同步信息是接收机实现定位、测速以及授时等功能的前提条件。为了满足这一需要,在分析导航电文结构的基础上,对特定格式下的导航电文进行研究设计,并根据相应的设计要求对每一步设计进行验证。该设计主要由导航电文生成模块和帧同步验证模块组成,通过Quartus II编程软件和Modelsim仿真软件协同仿真,完成对导航电文的设计、导航电文帧格式以及帧同步的验证。
The generation of navigation message and verification of frame synchronization are the most important parts of the signal simulator for short wave radio location,and obtaining proper navigation message and frame synchronization message is necessary for the implementation of positioning,velocity measurement and timing functions of receiver.To meet this requirement,the navigation message under specific format is studied and designed based on an analysis of the structure of the navigation message,and according to the corre-sponding design requirements,each step of the design is verified.The design is composed of the navigation message generation module and frame synchronization verification module,and the verification of the navigation message design,the frame format and frame syn-chronization is performed through a combination of Quartus Ⅱ and Modelsim.
