Communication Signal Simulation and Monitoring System Based on Software Radio

随着无线通信技术的飞速发展，通信环境日趋复杂，信号种类繁多、传输方式灵活多变，给通信系统的测试、验证与监测带来了巨大挑战。传统的信号发生与监测设备通常专用性强、灵活性差、成本高、难以适应多种通信标准与频段的快速变化。针对这一问题，本文设计实现了一种基于软件无线电的通信信号模拟与监测系统。该系统采用C++作为开发语言，通过编写代码设计一个自主、可控的通信信号模拟与监测平台，并利用双缓冲区技术，有效提高频谱和波形界面的渲染效率，为现代无线通信系统的开发与维护提供了强有力的支持。With the rapid development of wireless communication technology, communication environments have become increasingly complex, with a wide variety of signal types and highly flexible transmission methods. This poses significant challenges for the testing, verification, and monitoring of communication systems. Traditional signal generation and monitoring equipment tends to be highly specialized, inflexible, costly, and poorly suited to the rapid evolution of various communication standards and frequency bands. To address this issue, this paper designs and implements a communication signal simulation and monitoring system based on software-defined radio (SDR). The system is developed in C++, creating an independent and controllable platform for communication signal simulation and monitoring. By employing a double-buffering technique, it effectively improves the rendering efficiency of the spectrum and waveform interfaces, providing strong support for the development and maintenance of modern wireless communication systems.
