| 摘 要： | 从基本的双码交替二进制偏移栽波（AltBOC）调制模型出发，结合数学仿真深入研究双码AltBOC、标准AltBOC和恒定包络AltBOC调制原理；重点分析比较了标准Ait—BOC和恒定包络AltBOC调制技术的副载波特点、频谱特性及其对接收机设计产生的影响；利用查表法仿真实现无任何干扰情况下伽利略（Galileo）E5信号，进一步验证了将恒定包络AltBOC调制作为卫星导航信号调制方案的优势，为接收机设计中AltBOC信号的接收处理方式的确定提供了重要的理论依据。

| Abstract: | As to develop high-performance AltBOC receiver,based on 2-codes AltBOC(2-codes Alternate Binary Offset Carrier,2-codes AltBOC)modulation model and combined with mathematical simulation,the modulation principle of standard AltBOC and constant envelope AltBOC are in-depth studied.The characteristics of sub-carrier and spectral density performance of standard AltBOC are compared with these of constant envelope AltBOC,and focus on analyzed these effect on receiver design.Based on simulated Galileo E5 signal wit... |
