The utility model discloses a dynamic spectrum allocation system based on time granularity, including station operators, coupling matrix module, dynamic spectrum management module, database module, cognitive and non cognitive base station authorized user terminal; in the process of spectrum sharing, because of the economic interests of the incentive, without affecting the user authorization the quality of communication, by sharing the spectrum, maximize the benefits, which can be actively involved in the spectrum sharing; unauthorized users can also through sharing way, effectively alleviate the tense situation of spectrum resources. Finally, the effective utilization rate of spectrum resources is improved.
