Abstract: A method and apparatus for detecting a signal using a cyclo-stationary characteristic value is provided. A method of detecting a signal using a cyclo-stationary characteristic value includes: calculating cyclo-stationary characteristic values with respect to a cyclic frequency domain of an input signal; multiplying the calculated cyclo-stationary characteristic values with each other; and detecting the signal from the input signal based on the result of the multiplication.

Abstract: A method for managing a channel set for dynamic channel allocation, and a system for performing the method. The method includes predicting a channel state and a channel quality on a vacant channel based on channel information that is obtained by spectrum sensing and communication protocol. The predicting includes modeling an occupation pattern of the vacant channel to calculate a probability in which an incumbent user (IU) licensed to use the vacant channel appears on the vacant channel. The method also includes evaluating reliability on the prediction result, and giving a priority to the vacant channel based on the evaluated reliability.

Abstract: Provided are a method and an apparatus for managing a channel set in a cognitive radio (CR) communication system. A CR communication system for dynamically allocating frequencies or channels manages vacant channels regularly so as to set an appropriate priority to usage of the vacant channels such that a channel set can be managed efficiently.
