Abstract

Spectrum sensing, in particular, detecting the presence of incumbent users is no longer required for the operation of White Space Devices (WSD). However, detection of other opportunistic users using the same spectrum is still an open challenge. Generalized Frequency Division Multiplexing (GFDM) is a recent multicarrier modulation technique with extremely low out-of-band radiation that makes it an attractive choice for the PHY layer of cognitive radio. In this paper, we consider the problem of spectrum sensing by detecting GFDM based opportunistic users. Despite the fact that there is no incumbent transmission, an opportunistic user first senses the channel to make sure that no other opportunistic user is using the channel. In this work, the sensing characteristics of the opportunistic GFDM signal are obtained and analyzed in detail.
