Controlling Aggregate Interference Under Adjacent Channel Interference Constraint in TV White Space

TV White space, where secondary systems can be deployed inside the TV coverage area and utilize the geographically unoccupied TV channels, is considered as a promising solution to relieve the spectrum shortage. To utilize this spectrum, the secondary users must ensure the protection of TV reception from harmful interference on both co-channel and adjacent channels. In this paper, the authors propose an analytical approach to determining the permissible transmit power for short-range secondary users under aggregate adjacent channel interference constraint in TV white space.
