从软件无线电到认知无线电,走向终极无线电——无线通信发展展望

Software Radio,Cognitive Radio and Ultimate Radio——A Prospect of Wireless Communication

介绍软件无线电三种基本结构及认知无线电基本概念的基础上,提出了基于电子侦察原理的一种新的认知无线电实现架构及其对应的认知循环过程。同时,针对认知无线电存在的问题,提出了基于盲源分离的认知无线电——终极无线电(ultimate radio)的新概念,并对其实现的可行性进行了初步的分析讨论。

Through a review and outlook of three basic structures of software radio （SR） proposed by the author and the fundamental concept of Cognitive Radio （ CR）, the paper presents a new framework of CR and its corresponding cognitive cycle based on the principle of electronic reconnaissance. Furthermore, faced with the existing problems of CR, the author puts forward a new concept of SR-Uhimate Radio （UR） based on the theory of blind source separation （BSS）. The feasibility of realizing UR is also discussed.
