An interference analysis for coexistence of Femto-LTE in TV white space with various OOB level

To overcome a scarcity resources to mobile broadband service becomes serious across the world, the usage of TV white space gains much attraction around the world. This paper provides an interference to verify a probability of interferences between TV band devices (TVBD) based on Femto-LTE system operating in TV white space. In this study, we investigate to specify the parameters regarding TVBD emission mask as long as obeying minimum requirement of threshold of visibility (ToV). To show the validity of coexistence of Femto-LTE adjacent to DTV, the out-of-band(OOB) limit is adjusted to satisfy 3% interference probability. In simulation results, the plausible OOB levels of Femto-LTE systems are provided for the coexistence in adjacent frequency band.
