摘 要:针对现代无线通信系统的多标准多体制要求,高效、快速并相对低成本地对大量信号和数据进行处理变得越来越重要,软件无线电技术由其易修改和低成本的优势,把无线通信技术提升到一个软件化易扩展的新高度。利用通用的软件无线电平台,在GNU Radio编程环境中完成了基于HackRF的无线通信收发系统。阐述了GNU Radio编程环境及HackRF的功能及构成,随后在对GMSK调制系统建立基于单机的实验仿真并成功完成的基础上,以GNU Radio+HackRF为模型,进一步设计并实现了无线视频流的传输,从而实现了基于软件无线电平台的无线通信。从实验结果得出,此系统可以较好地发送并接收视频流信号。For the multi-standard and multi-system requirements of modern wireless commun-ication system,efficient,fast and relatively low cost of a large number of signals and data processing is becoming increasingly important,Software defined radio has the advantages of easy to modify and low-cost,it upgrades the communication technology to software and expandable in height.The wireless communication transceiver system based on HackRF is designed by using universal software radio platform and GNU Radio programming environment.This paper introduces the functions and structure of GNU Radio programming environment and HackRF.The simulation of GMSK modulation system based on stand-alone is established and successfully completed,With the GNU Radio+ HackRF,aprototype of wireless video transmission system was realized based on the link module with the real wireless channel.The experimental results show that the designed system can send the received video signal better.
