摘要
介绍了直接序列扩频收发信机的设计原理,重点叙述了伪随机序列捕捉和跟踪的设计方法,提出了一种基于软件无线电技术的全数字直接序列扩频系统的设计模型,并进行了仿真,提出了硬件实现框架。
Introduces the principal and design of direct-sequence spread spectrum(DSSS) tranceiver. In detail, analyzes the acquisition and tracking method of PN synchronization loop.A model of digital DSSS system is provided on the basis of software radio technology. Finally, the model is simulated and hardware implement frame is presented.
