前景光明的软件无线电技术

Auspicious Software Radio Technology

软件无线电技术是在通用的开放式无线电智能平台上,通过安装不同的软件来完成各种通信功能.软件无线电系统适用于多个频段,可灵活地改变工作模式,能与不同体制和标准的各种设备互通和兼容.软件无线电的关键技术包括多频段多波束天线、宽带射频(RF)信号处理、宽带A/D变换和高速数字信号处理等.目前可实现的软件无线电系统水平较低,但这一技术已在军事和商业无线电系统中被越来越多地采用,必将成为移动通信中的主流技术.

Software radio technology realizes various communication functions through installing different software on a universal open radio intelligent platform. Software radio system is applicable to multiple frequency bands and it can change working mode flexibly. The system can interwork and is compatible with various equipment of different systems and standards. The critical technologies of software radio including multi-band multi-beam antenna, broadband RF signal processing, broadband A/D conversion and high-speed digital signal processing, etc. Although current realized software radio system could not reach quite high level, this technology is increasingly applied in military and business radio systems . It will inevitably become the mainstream technology of mobile communication.
