首发时间:2011-10-27
摘要:本文伽利略卫星导航系统信号的调制进行了研究以及仿真。为了模拟产生伽利略信号源,首先对编码进行研究,了解伽利略扩频码的编码特性,并对其进行matlab仿真,验证其正确性,分析频谱特征了解其优良的抗干扰特性,再对E5信号的进行调制,并进行matlab仿真实现,为下一阶段源的硬件实现和进一步的伽利略接收机的设计打下良好的基础。

Galileo satellite navigation system E5 signal modulation and matlab simulation
Abstract:In this paper introduced signal modulation and simulation of Galileo satellite navigation system. In order to generate Galileo signals analog source, at frist study to understand the encoding characteristics of the Galileo spreading code and simulate by matlab to verify its evidence correctness, analysis of spectral characteristics to understand the excellent anti-jamming features. Then is the E5 signal modulation and implementation in simulation, it's good fundation to source of the hardware implementation and design of Galileo receivers.
Keywords: Signal and Information Processing Galileo signal modulation matlab simulation
