| Abstract(in English) | It becomes a problem of low communication speed at narrow space with several wireless communication for example of wireless IoT in smart factory in order to conflict of these signals. This problem of sommunication speed causes low productivity. A real-time broadband spectrum sensor is neccesarry for this problem to observe broad band (920MHz/2.4GHz/5GHz wireless IoT bands). We develop a new simple real-time and broadband spectrum sensor for this problem. A several sampling frequency undersampling method, implementation of transient time of sampling frequency changing for real-time characteristics, implementation of sampling freiquency and number of sampling for broadband spurious-free characteristics. We succeed to develop a new simple real-time and broadband spectrum sensor and spectrum sensing for wireless IoT bands is able to be obtained consequently. We also proceed a node-position sensing method using this spectrum sensor equipment. |
