Method for sensing spectrum and arranging quiet period in cognitive radio system, customer premise equipment, base station and superframe structure using the same

摘要

that the spectrum sensing method in a wireless system , transmitting the alignment idle period , the terminal therefor , a base station and a super the frame structure is disclosed. This is a communication step of performing communication with the base station ; And transmitting each idle period of the frequency channels used by the cognitive radio system , comprising a sensing step of performing spectrum sensing for a frequency channel having a rest period and the transmission , the transmission of each frequency channel idle period is not overlapped with each other the features . According to the invention , in the cognitive radio system can detect whether the appearance , thereby increasing the reliability of the original user (Incumbent User).
