摘要

中文摘要: 为了接收临近空间高动态高信息速率用户信号，需要设计载波链路的捕获与跟踪系统。根据临近空间网络高动态高信息速率的链路特性，着重分析了HDHI（HDHI，high dynamic and high information rate）载波链路捕获跟踪的特性及实现方案。对载波链路捕获跟踪的设计原理做了清晰的说明和推导，提出了适合HDHI载波链路捕获跟踪设计方法，并对高动态高信息环境中接收机的载波捕获与跟踪数字系统的设计做了详细的陈述。最后通过实验和对比论证了利用DQPSK方式的HDHI信号捕获跟踪设计方法是可行的。

Abstract

Abstract:To receive high dynamic and information rate user signal in near space

it is necessary to design carrier acquisition and track system. According to the high dynamic and information rate characteristics of wireless link in near space

the performance and implement scheme of carrier acquisition and track were analyzed. The design principle of carrier acquisition and track under high dynamic and information rate situation was explained and deduced clearly. A new suitable method was proposed for high dynamic and information rate wireless link.The design method of digital receiver system was described in detail under high dynamic and information rate situation.The results of experiment and comparison showed that the design method of carrier acquisition deriving from DQPSK under high dynamic and high information rate situation was available.
