Research on Application of OFDM Technology in Cooperative Spectrum Sensing
Cognitive radio (CR) is viewed as a novel approach for improving utilization of the precious radio spectrum. Spectrum sensing is one of the most important technologies in cognitive radio. A general presentation of OFDM technology and cooperative spectrum sensing are given in the first instance. In order to improve detection probability and reduce equipment complex and computation complex, to combine OFDM technology with the cognitive radio, on top of analyzing the application of OFDM technology in cooperative spectrum sensing, the authors advance collaborative sensing method based on energy detection and OFDM. Simulation and analysis results show that the method can effectively improve detecting spectrum holes probability.
