随着移动通信领域出现了多个不同的标准,尤其是3G时代的到来,不同标准的终端之间的互联互通问题日益突出。本文利用联合处理的方法,提出了硬件可重构的软件无线电平台,通过改变系统的特性来快速适应不同的通信体制。这一平台通过在三个维度上应用联合处理方法:处理手段上的软硬件联合处理;处理域上射频、中频和基带联合检测与识别;在功能分类上的传输、接入、安全、重构四种功能合作。这一平台基于现有技术的水平,高效的实现了包含射频前端在内的多种通信体制的可重构。
With the emergence of many different standards in the field of mobile communications, especially the advent of the 3G era, interoperability issues between terminals of different standards have become increasingly prominent. In this paper, a joint reconfigurable software radio platform is proposed, which can quickly adapt to different communication systems by changing the characteristics of the system. This platform uses a joint approach in three dimensions: joint processing of hardware and software on the processing means; joint detection and identification of radio frequency, intermediate frequency and baseband on the processing domain; transmission, access, security, refactoring Four kinds of functional cooperation. Based on the current state of the art, this platform efficiently reconfigures a variety of communication systems including radio frequency front end.
