认知无线电技术的国内外发展与研究现状

为了研究认知无线电技术的国内外发展现状,对从1999年至2008年的所有的IEEE中有关认知无线电技术的文章进行了统计分析,用表格形式展现了总体研究情况、系统/结构的设计、频谱感知、频谱决策、频谱共享、频谱切换等几方面的研究现状,并对文章的研究内容、目前可供研究的开放性等问题进行了总结和分析,最后统计了各国研究机构和大学在认知无线电研究领域的情况统计结果显示目前对系统/结构设计、频谱感知和频谱共享三方面的研究较多,而对其他方面研究较少;美国、欧洲和中国在认知无线电技术方面取得了一些成果

Survey on development and research of cognitive radio networks at home and abroad

In order to study the development status of cognitive radio technology at home and abroad, a statistical analysis on the papers about cognitive radio technology in IEEE from 1999 to 2008 was proposed. Using the form of table, the overall research status, system/architecture design, spectrum sensing, spectrum decision, spectrum sharing, and spectrum switch were shown. Furthermore, these papers' research contents and openness for further study were summarized. At last, an overview of the cognitive radio researches in different research institutes and universities of world was presented. Statistical analysis shows that there are more researches on system/structure design, spectrum sensing, and spectrum sharing, but the researches on the other aspects are poor, and America, Europe, and China have made some progress in cognitive radio technology.
