摘要
无线通信系统往往采用不同的制式、工作在不同的频段,因此无法互通和兼容。软件无线电技术通过构造一个具有开放性、标准化、模块化的通用硬件平台,用软件来完成各种功能,可用于研制具有高度灵活性和开放性的新一代无线通信系统。介绍了软件无线电的基本结构和关键技术,然后分别叙述了软件无线电在cdma1x基站和3G中的应用,最后指出了软件无线电技术在3G中的重要性。
Since different systems and frequency bands are used in different wireless communication systems,inter-communication and compatible be-tween them are difficult.Through the construction of a opening,standardiza-tion and modularization general hard-ware platform,software radio technolo-gy can implement functions through software.It can be used to research on new generation wireless telecom system with high flexibility and opening.Basic structure and key technologies of soft-ware radio are introduced.Then appli-cation of software radio in cdma 1x base station and3G are described.Finally,importance of software radio technolo-gy in3G is pointed out.
