Abstract
An apparatus for detecting a signal in a common frequency band includes: a signal processor configured to extract a selected band signal from received wireless signals by filtering the received wireless signal based on a frequency selection control signal, convert the extracted signal to a baseband signal, and detect a predetermined signal; a sensing signal determiner configured to determine existence of the signal, output a determination result, and outputs a frequency selection generating signal when the predetermined signal is absent; and a frequency selection controller configured to output the frequency selection control signal by selecting a target band among a plurality of previously decided bands.
