摘要
软件无线电通过软件来建立一种灵活的无线电系统,可实现多种服务,适应多种标准,覆盖多个频段,而且可重构和重新编程,通过软件下载,使用户能随时随地适应他所在的无线电环境。在介绍软件无线电体系结构的同时,依据其体系结构,从软件无线电相关技术目前的发展情况出发,分析了软件无线电所面临的技术问题,并对相应的解决方案进行了研究,其中包括智能天线、DSP技术、宽带ADC等在软件无线电中的应用问题。
The software radio is to build flexible radio systems, multiservice, multistandard, multiband, re-configurable and reprogrammable by software. A software implementation of the user terminal is able to dynamically adapt to the radio environment in which it is, time by time, located. In this article, the architecture of software radio is objectively introduced, and the technological challenges are analyzed according to its architecture and the development of related technologies. At the same time, the corresponding solutions are studied, including the application of smart antenna, DSP technology and wideband ADC in the software radio.
