ENERGY DETECTION APPARATUS

摘要

According to an embodiment of the present invention, an energy detection apparatus enables to easily determine the type of a communications system with an energy pattern map (MAP) produced from the energy information received from an available radio frequency. The energy detection apparatus includes an energy detecting unit for detecting the energy information corresponding to an arbitrary signal received between at least one or more communications systems based on a cognitive radio (CR) technology; an energy pattern producing unit for producing the energy pattern map (MAP) for a set period of time on the basis of the energy information; and an energy determining unit for determining an arbitrary communications system which generates the arbitrary signal among the communications systems on the basis of the energy pattern map and the pattern information stored previously when arbitrary pattern information corresponding to the energy pattern map is stored.
