ITU-T G.100.1-2015 语音频带电信中分贝和相对水平的使用(研究组12)

In transmission engineering, most often it would be rather impractical to characterize the magnitude of signals directly by a numerical value in volts or watts. Instead, a logarithmic measure is used, expressed in "dB", to characterize the signal magnitude in relation to some chosen reference value.

ITU-R SM.1370-2-2013 显影自动频谱管理系统的设计指南

This Recommendation gives design guidelines for an automated spectrum management system, including the recommended functionality for such a system, and the data elements required for frequency management at national level while also ensuring the data is collected to meet the international obligations for frequency coordination and notification.

ITU-R SM.2039-2013 频谱监测发展

This Recommendation gives a brief introduction on the evolution of spectrum monitoring and recommends requirements and technologies to be considered to support the evolution of spectrum monitoring.

Spectrum monitoring evolution

ITU-R SM.1537-1-2013 自动频谱管理的频谱监测系统的自动化和集成

Current technology allows most spectrum monitoring functions, and indeed entire monitoring stations, to be highly automated, and allows spectrum monitoring systems to be highly integrated with automated spectrum management. Many activities of an automated national spectrum management system will benefit from integration with automated spectrum monitoring stations. This Recommendation describes recommended functionality of these systems.

ITU-R SM.1603-1-2012 频谱调度作为国家频谱管理方法之一

This Recommendation gives guidelines for spectrum redeployment issues. The ITU Radiocommunication Assembly considering a) that all administrations need to make spectrum available for new radio applications and for increased use of existing applications; b) that as the use of the spectrum increases it may become progressively more difficult for administrations to find suitable spectrum for radio applications; c) that making spectrum available for some new applications may require redeployment to other frequency bands or redeployment to new technologies (i.e. to decreased bandwidth or analogue to digital); d) that redeploying licence-exempt bands will be complicated by lack of records of users; e) the experiences of administrations in spectrum redeployment techniques would provide information on the practice; f) that frequency management and thus redeployment of spectrum is a national responsibility and there is a need for guidelines by collating the experiences of administrations in spectrum redeployment techniques.
