软件无线电技术及其在军事领域的应用

摘要

软件无线电是一种用高速数字信号处理器上的软件设计取代专用硬件电路模块的无线通信系统,具有灵活多模可重配置易升级等优点.首先阐述了软件无线电的概念、特点和体系结构,并依托未来数字化战场的变革,探讨了软件无线电技术在军事领域的广阔应用前景.最后基于清华大学软件无线电统一平台进行了波形开发,实现了可重构卫星通信平台上的一种通信体制.%Software Defined Radio (SDR) is a radio communication system where components that have been implemented in specific hardware circuits are instead implemented using software on high-speed digital signal processors, This system has some advantages like flexible, multi-mode, reconfigurable and easy to upgrade. The SDR related concepts, characters and architecture is introduced . Relying on the change of future digital battlefield, the broad application prospects of SDR in the military field have been investigated. Finally, based on the unified SDR platform developed by Tsinghua University, a waveform is conducted to realize a specialized communication system in the reconfigurable satellite communications platform.
