摘要
认知无线电技术是认知科学和信息科学相结合形成的一个崭新的学科,是一种具有频谱感知和智能决策能力的软件无线电。本文对传统导航定位系统的接收结构进行了分析,阐述了基于认知无线电技术进行导航信号识别的理论基础,构建了一种认知导航定位系统接收结构。
Cognitive ratio（CR） technology is formed based on cognitive science and information science. CR can be seen as software-defined radio with the capability of spectrum sensing and intelligent decision. This paper analyzes the receiver structure of traditional navigation positioning system and the theoretic basements of cognitive navigation receiver. And then, this paper builds a kind of cognitive navigation receiver based on CR technology.
