In this paper, we propose a new multi-channel transmission strategy for dynamic spectrum access in cognitive radio network. Starting with the model of spectrum activities, we present the multi-channel transmission strategy which has primary user's protection mechanism to improve the spectrum efficiency and study its performance under perfect and imperfect sensing. Numerical example results reveal that the performance of the proposed strategy has the superiority with respect to capacity performance of cognitive users and the protection of primary users.展开更多

The concept of culture and complicated contents as simply includes material culture and spiritual culture. Cultural inheritance is the process of acculturation a nation it not only is the transmission of national culture, the inheritance and development that also can be refl ected by many indexes. Multicultural education theory formed in the American civil rights movement in the 1960s. Multicultural education theory is that, when the mainstream national culture and the minority subculture in contact, every culture shall be entitled to retain their own cultural traits. Our research integrate the regression and inheritance of culture to then propose the innovation strategy research of the Yunnan image that will promote further development of the corresponding and related industry.展开更多
