Novel Spectrum Sensing for Cognitive Radio Based Femto Networks
In this paper, we propose spectrum sensing technique in TV white space (TVWS) for cognitive radio (CR) based femto networks. The spectrum sensing is performed based on digital watermarking technique. The performance is analyzed and simulated in terms of detection probability. From the simulation results, it is confirmed that the proposed scheme achieves better detection performance compared with other sensing algorithm.
