新一代卫星导航系统的多信号接收软件

A Multi-signal Software Receiver for New Satellite Navigation System

随着全球卫星导航系统的发展,卫星导航接收信号向多元化方向迈进,为此对接收机接收信号的多样性及其兼容性提出了更高的要求。设计了一种新一代卫星导航系统的多信号接收软件,该接收软件采用对接收信号在导航系统类型、信号调制方式和信号频段进行模块化处理的方式,实现了在不同的环境下对特定信号同步接收。同时,该接收机利用VC平台丰富的界面显示效果和Matlab平台强大的数学计算能力的特性,既能保持传统硬件接收机高效的处理速率,又能发挥软件接收机参数可变、快速灵活的特点。

With the development of global satellite navigation system, satellite navigation signals gradually develop into diversification, which has higher requirements for the receiver with its compatibility with multi-signal. A multi-signal software receiver is designed for new satellite navigation system. The software receiver uses a variety of methods to improve the reception signal like a modular processing of navigation type system, the modulation of signals and the band of signals, which meets the requirement of receiving particular signal in different circumstances. Meanwhile, abundant display effects of VC are adopted and Matlab＇ s powerful ability is applied in mathematical calculation. The software receiver can not only work like traditional hardware receiver with efficient processing rate, but also contain variable and flexible features of parameter.
