认知无线电标准化进展

Standardization Status of Cognitive Radio

认知无线电技术的出现,为解决频谱资源不足、实现频谱动态管理及提高频谱利用率提供了强有力的技术支撑。随着认知无线电技术的发展,各标准化组织和行业联盟也纷纷开展相关的研究,并且开始着手制订认知无线电的标准和协议。美国电气电子工程师学会(IEEE)、国际电信联盟(ITU)和软件无线电(SDR)论坛是研究认知无线电相关标准的主要组织和行业联盟,相关的标准制订工作推进了认知无线电技术的发展和应用。

The cognitive radio technology provides a strong technical supportto resolve spectrum resource scarcity; it implements dynamic spectrum management and improves spectrum efficiency. With the development of cognitive radio, many standard organizations and industrial Unions have initiated pertinent research, and constituted corresponding standards and protocols. The Institute of Electrical and Electronics Engineers （IEEE）, the International Telecommunication Union （ITU）, and the Software Defined Radio （SDR） Forum are the main bodies whose researches promote the development and application of cognitive radio.
