摘要
为了提高Chirp通信系统的传输速率,本文采用多带Chirp信号作为信息传输的载体来实现多带Chirp通信系统。而实现高速多带Chirp通信系统的关键是接收端多带Chirp信号的检测,基于GNU Radio和USRP X310平台,分析了多带Chirp信号的检测方法。与纯硬件实现多带Chirp信号检测相比,使用Python脚本语言和GNU Radio中的软件模块,具有实现简单、开发周期短、复杂度低等优点。最后通过GNU Radio和USRP X310实验平台对多带Chirp信号检测方法的可行性进行了实验验证。实验结果表明,该检测方法能够有效地实现多带Chirp信号的检测。
In order to improve the information transmission rate of Chirp communication system,using a multi-carrier band Chirp signal as the transmission of information to achieve multi-band communication system Chirp.Chirp-speed multi-band communication system is key to achieving the receiver of multi-band Chirp signal detection.Multi-band Chirp signal detection method is analyzed based on GNU Radio and USRP X310 platform,which has much superiority such as easier to realization,shorter of system development cycle,lower complexity,etc than pure hardware.Finally,the feasibility of multi-band detection method validation experiments on GNU Radio and USRP X310 platform.Experimental verification on GNURadio and USRP X310 has been accomplished.
