| Abstract(in English) | We have proposed the orthogonal frequency sensing information collection method which collects the sensing information of multiple sensing nodes to the master node. The method converts the received power level into the frequency of narrow band orthogonal signal, which corresponds to OFDM subcarrier number. This method can effectively collect the cooperative sensing information to the master node by using the same channel with the primary system, because it uses only the narrow band signal which can reduce the interference toward the primary system compared to using the whole band of the primary system. In this research, in order to protect the primary system, the secondary node controls the transmit power considering the total power of the primary system. Then we can realize the information collection method by using the same spectrum. Finally, we confirm the effectiveness of our proposed method by evaluating the inter system interference between the primary system and the secondary system. |
