Abstract

Software defined radio (SDR) is an exciting merger of digital signal processing and wideband radio hardware. The term SDR came into more common usage in 1992 by Dr. Joe Mitola, but actually had its beginnings back in 1984 at E-Systems. The ideal SDR receiver consists of an antenna connected to an analog-to-digital converter (ADC) followed by a digital signal processing system (DSPS) to extract the signal of interest. Low-cost, as in $20, SDR receivers originally designed for digital video broadcasting, have been available for several years. Giving undergraduate students hands-on experience in this area is needed. In this paper we describe the details of an SDR laboratory experiment for students in a first semester communications theory course. Complete open-source SDR receiver software is used to get started, then coding of DSP algorithms is explored to process captured radio signals generated using test equipment and then actual over-the-air broadcasts. Being able to write code to process live signals and then see and hear the results really connects with the students. Both Matlab and Python support code libraries are available.

动手软件定义无线电实验与低成本的RTL-SDR加密狗

软件定义无线电(SDR)是数字信号处理和宽带无线电硬件的令人兴奋的结合。SDR一词在1992年被Joe Mitola博士广泛使用，但实际上早在1984年E-Systems就已经开始使用了。理想的SDR接收机由连接到模数转换器(ADC)的天线和数字信号处理系统(dsp)组成，用于提取感兴趣的信号。最初为数字视频广播设计的低成本SDR接收机，售价20美元，已经有好几年了。让本科生在这一领域获得实践经验是必要的。本文以通讯理论课第一学期的学生为对象，描述了一个特别提款权实验的细节。使用完整的开源SDR接收机软件开始，然后探索DSP算法的编码，以处理使用测试设备产生的捕获的无线电信号，然后进行实际的空中广播。能够编写代码来处理实时信号，然后看到和听到结果，这真的与学生们联系在一起。Matlab和Python都支持代码库。
