认知无线电技术及应用

Cognitive Radio Technology and Its Application

随着科技的发展和社会的不断进步,我国在科技领域取得较大成就。综合当下的国情来看,无线电传输领域当下最重要的研究对象就是认知无线电技术。在无线电技术日益普及的情况下用户,对无线电的需求越来越多,现有的频谱资源已无法满足人们的需求。在无线电资源较为匮乏的当前社会中,如何全面提升无线频谱的利用率,是当下我国无线电技术发展中面临的重要难题,也是发展中面临的重要挑战。笔者通过探析无线电技术的各种定义,发现了无线电是由认知无线电的组成和技术的应用两个方面构成的,通过对认知无线电的关键技术进行探究,得出了认知无线电具有巨大的发展潜能。

With the development of science and technology and the continuous progress of society,China has made great achievements in the field of science and technology.In the light of the current national conditions,the most important research object in the field of radio transmission is cognitive radio technology.With the increasing popularity of radio technology,the demand for radio is increasing,and the existing spectrum resources have been unable to meet the needs of people.In the current society where radio resources are scarce,how to improve the utilization of radio spectrum comprehensively is an important problem in the development of radio technology in our country,and it is also an important challenge in the development.The author through the discussion of various definitions of radio technology,finds out that the radio is composed of two aspects of the composition and application of cognitive radio technology,explores the key technologies of cognitive radio,concludes that the cognitive radio has great development potential.
