Spectrum sensing (SS) plays a significant role in cognitive radio network. In our work, we focused on FPGA (Field Programmable Gate Array) implementation of SS applying for DVB-T (Digital Video Broadcasting — Terrestrial) signal detection because TV band has been considered for the operation of cognitive users (unlicensed users) by Federal Communications Commission (FCC). The OFDM signal (Orthogonal...
In cognitive radio network (CR), spectrum sensing (SS) is regarded as a critical component. Several local SS schemes have been studied well in the literature to locate spectrum holes for reusing it. However, the system's performance will be degraded seriously over the fading environment. The cooperative spectrum sensing techniques were proposed to improve performances of signal sensing. In this paper,...
