Dynamic BEM implementation in interference analysis by original and optimize problem in TV-band whitespace

초록

In TV-band white space, the digital television (DTV) spectrum always make free or no-use spectrum when performing its actions in its spectrum range. So that, TV band devices (TVBDs) wishes to use this spectrum but not cause the harmful interference to DTV system. Besides, DTV spectrum can tolerate the interference from other system with their threshold. The sharing spectrum regulation that guarantee the interference between communications system was characterized in Federal Communications Commission (FCC), Advanced Television Systems Committee (ATSC) and Electronic Communications Committee (ECC) for DTV system. Based on these specifications, this paper will propose one method that applies dynamic Block Edge Mask (BEM) into Interference Analysis for DTV band whitespace. Using of Genetic Algorithm (GA) will implement the method that allows us to solve the intelligent BEM for DTV which proposes the criterion to get the optimal emission level to avoid harmful interference caused by other wireless systems with specified transmission power and geo-location arrangement. © 2013 IEEE.
