    摘要： A low-complexity dynamic channel allocation apparatus and method in a multi-carrier communication system are provided. In the low-complexity dynamic channel allocation method, subcarriers are initially allocated to total users and two users are selected from among all possible cases of two users out of the total users. The power gain of each of the subcarriers initially allocated to the selected two users is calculated, which can be generated by reallocating each subcarrier to the other user through subcarrier swapping. The power gains of the initially allocated subcarriers are ordered for each of the selected users and a pair of subcarriers with the greatest power gains for the two users are selected. Subcarriers are reallocated to the two users by swapping the selected subcarriers between the two users.

    摘要： One embodiment disclosed in the present description relates to a coexistence manager which can adaptively select channels in a coexistence environment between disparate systems with channel use constraints that inherently exist with use of TVWS. Accordingly, the embodiment disclosed in the present description provides a resource allocation method for a manager device, comprising the steps of: receiving a channel allocation request from a first network or device; determining a second network or device for switching channels based on the benefits of each channel or device, if a channel cannot be assigned to the first network or device; switching the channel used by the second network or device to another channel and raising its priority; and assigning the channel used by the second network or device to the first network or device.

    摘要： An embodiment of the present invention relates to a method for performing spectrum sensing to detect a signal for a terminal of a primary user in each sensing node. The method for performing sensing may comprise the steps of: performing, by the sensing node, spectrum sensing to detect a signal for a terminal of a primary user; computing, by the sensing node, a local test statistic on the basis of the result of the spectrum sensing; calculating, by the sensing node, the transmission probability on the basis of the computed local test statistic; and transmitting, by the sensing node, sensing information to a convergence center on the basis of the calculated transmission probability. In this case, the convergence center can determine whether the signal for a primary user exists on the basis of the transmitted sensing information.
