摘要
通信和其他信息处理技术的实现,在过去的一段时间里经历了从模拟到数字的变革,当前又正处于从硬件实现到软件实现的改变。软件无线电是一种新型的无线电体系结构,作为一种设计方法它已被广泛用于通信和无线电工程的相关领域。它可以通过运行不同的软件算法,实时配置系统的通信功能,从而提供不同的无线通信业务,能方便地实现原型设计向实际应用的过渡。因此,基于软件无线电教学平台的通信实验适应了当前的变革趋势,有利于学生深入掌握通信基本原理,进行可重构的模块化设计,模拟通信收发机制和信道模型,快速搭建整体通信链路。
The implementation of communication and information processing technology, in the past period of time, has been experienced from analog to digital transformation, and now is from hardware to software changes. Software Defined Radio (SDR) is a new type of radio system structure. As a kind of design method it has been widely used in communication and radio engineering related fields. It can run different software, complete many algorithms and configure the functions of the communication system in real time. Hence, a variety of wireless communication services are provided. It can easily implement a prototype design to the actual transition. Therefore, communication experiments based on software radio teaching platform can benefit to students to deeply understand the basic principles of communication and to make its prototype design which is reconfigurable rapidly.
