摘要
由于无线通信技术的飞速发展,以及硬件组成性能的限制,当前主流的一些软件无线电(Software Defined Radio,SDR)外设已不能满足无线电研究人员的需求。基于一种面向5G通信自主开发的软件通用平台(Software Universal Platform,SOUP)和无线电软件开发平台GNU Radio,设计搭建了一种符合软件通信架构(Software Communication Architecture,SCA)的软件无线电系统。使用硬件驱动程序PDMA使主机识别SOUP、屏蔽SOUP底层硬件的实现细节,并使得操作系统能够像操作文件一样对SOUP进行操作,再使用GNU Radio的模块开发工具开发出信号源模块和信宿模块,这2个模块的功能就是用来采集和传送I/Q采样信号。通过实现一种传统的模拟通信系统,以验证SOUP_GNU Radio系统的有效性。
With the rapid development of wireless communication technology and due to the limitation of hardware composition and performance,some mainstream Software Defined Radio(SDR) peripherals cannot meet the needs of radio researchers.Based on a Software Universal Platform(SOUP) and a radio software development platform(GNU Radio),a software defined radio system conforming to the Software Communication Architecture(SCA) is designed and built.Hardware driver PDMA is used to make the host recognize SOUP and shield the implementation details of the underlying hardware of SOUP,so that the operating system can operate SOUP like operating files.Then the signal source module and the sink module are developed using the module development tool of GNU Radio.The functions of these two modules are to collect and transmit I/Q signals.Finally,a traditional analog communication platform is implemented to verify the effectiveness of SOUP_GNU Radio system.
