In this paper, we research how to aggregate and allocate spectrum fragments of TVWS for Femto Base Stations (FBSs) in order to make full use of the nonuniform interference relationship between them. A database architecture control entity is introduced. Assisted by the entity, interference relationship between FBSs can be obtained in a cognitive manner and a distinctive graph coloring model considering...
In order to utilize TV White Space (TVWS) by deploying the cognitive radio technology and eliminate interference to digital television (DTV) system, some researches set extra isolation which may reduce spectrum efficiency. In this study, power control is used. However, the existing TD-LTE power control algorithms are not proper for the coexistence of TD-L TE and DTV systems because the interference...
