| Abstract(in English) | In recent years, owing to its benefit of improving network connectivity and flexibility, wireless multi-hop relay network has been attracting much attention with many promising applications in sensor networks and utility networks. When wireless multi-hop relay network is in operation as a secondary system, however, a spectrum sharing mechanism with the primary system should be employed. To achieve high spectral efficiency, it is required to recognize spectrum usage condition of the primary system by spectrum sensing and to assign available spectrum to the secondary system. In this paper, a spectrum sensing mechanism for 950MHz low power active radio system using FFT is proposed, and a hardware prototype employing the proposed mechanism is implemented. |
