In this paper,  the dynamic spectrum sensing was achieved by jointing cooperation spectrum sensing based on compression sensing. The last result of spectrum decision was made by comparing the hyper-parameters obtained from the fusion of the sensing  data with the decision threshold. The proposed algorithm reduces the uncertainty of the compression sensing data obtained by a single SU, results in a better performance of the normalized MSE, and can effectively excavate the compression sensing data of SUs. Compared with other typical algorithms, it can obtain higher correct detection probability and smaller false-alarm probability.
