TV White Space Database and Augmented Sensing Algorithmic Research

Abstract

Although the space resources are rather scarce, the research shows that the spectrum efficiency of the current spectrums is very low in China. This article presents an available method to construct TV white space database and an efficient augmented sensing algorithm based on the database. The goal is to sense the spectral distribution at a given location. To verify the proposed method is feasible, we only take a fixed area into account. In this paper, we selected some of the cellular-base-stations in an urban area to construct the database, and we can get the spectral distribution of an arbitrary location in the city. The results show that our database can give a quick response once a request comes, and it can display the accurate spectrum distribution of the area.
