Novel CR signal detection algorithms for coexistence in TV white space

Abstract

In this paper, we propose novel signal detection algorithms for coexistence of CR systems in TV white space. As various CR standards appear in TV white space, technologies for detecting CR signals are required to enabling coexistence between CR systems. The proposed signal detection algorithms detect and classify CR networks utilizing cyclo-stationary features of each CR system. They consider multiple periodic properties of OFDM signal which is varied by parameters of each CR standard. The simulation results show that the proposed schemes can improve signal detection performance up to 50% compare with the conventional schemes.
