In order to solve recognition of modulation signals, which is an important issue in cognitive radio, the paper proposes a new algorithm of recognition of modulation signals. The paper firstly analyzes a new algorithm of cooperative sensing and simulates it in low SNR. Secondly, it proposes new expressions of transient characteristic parameters and shows the procedure of how to define the thresholds. Finally, this paper shows and analyzes the simulation results. The simulation results show that the new algorithm of cooperative sensing has good detection performance. The transient characteristic parameters proposed in the paper have strong anti-noise ability and they can be as robust signatures. |
