Abstract

Low-cost electronic devices have become popular in the research, educational and industrial sectors. This has permitted to avoid the acquisition of expensive specialized equipment. In electronics communications, low-cost devices can be seen in the Software Defined Radio (SDR). This technology permits having a communications system in a single device to work over different frequencies. Commercial examples are HackRf One and LimeSDR, they can be configured using GNU radio. However, this software does not allow the proper understanding of communication processes. Seeking to improve the understanding of communications, this work presents a software development to transmit digital signals considering an SDR. The proposal generates baseband signals, digital modulation schemes such as QPSK, ASK, FSK, and constellation maps. Also, it is possible to appreciate the Power Spectral Density (PSD), modulation of signals in real-time and modify the parameters of the transmission. This contribution can be considered in teaching and research, among others.

基于软件定义无线电设备的数字信号传输软件开发

低成本的电子设备在研究、教育和工业部门变得流行起来。这样就可以避免购置昂贵的专门设备。在电子通信中，低成本设备可以在软件定义无线电(SDR)中看到。这项技术允许在单个设备中使用不同频率的通信系统。商业示例是HackRf One和LimeSDR，它们可以使用GNU无线电进行配置。然而，该软件不允许正确理解通信过程。为了提高对通信的理解，本工作提出了一种考虑SDR的传输数字信号的软件开发。该方案生成基带信号、QPSK、ASK、FSK等数字调制方案和星座图。此外，还可以实时测量信号的功率谱密度(PSD)、调制和修改传输参数。这种贡献可以在教学和研究等方面加以考虑。
