摘要
扩频通信技术具有抗干扰,抗多径,保密性好,不易被截获以及可以实现码分多址等优点。信号发生器是一种十分重要的仪器,在通信、测控、导航、雷达、医疗等领域有着广泛的应用。文章以直接频率合成和伪随机码的设计与实现为中心,对扩频通信的基本理论,载波调制等问题进行分析与研究。
Spread-spectrum communication has many advantages such as anti-jamming,anti-multipath,confidentiality,difficult to be intercepted,code division and multiple access,and so on.Signal generator is so important a device that it is applied to communication,monitoring and control,navigation,radar,medical and other abroad fields.In this paper,the design and achievement of direct digital frequency synthesize and pseudo-random code is central work,with basic theory of spread-spectrum communication and carrier modulation analyzed and studied.
