Due to the continuous expansion of wireless communication services , resulting in extremely scarce radio spectrum resources .National spectrum allocated to the broadcasting industry , some not good use of them . These white spectrum resources untapped , because with good propagation characteristics , so as to be commu-nications operators concern and attention .Now, on TV white spectrum resources research , development and u-tilization , it is conducive to the development of the wireless telecommunications industry , but also to China“triple play” offers help.This article introduces the definition TV white spectrum , and the importance of re-search and development of the white spectrum .Cognitive radio technology is the use of TV white spectrum premise .This paper reviews the several main spectrums sensing technology .Compare the pros and cons of sev-eral spectrums sensing technology .Finally, the article describes the white spectrum in Nanjing Broadcasting major broadcast application , as well as the subsequent application .
