Abstract: The article presents the results of the efficiency analysis of sensing for the OFDM (Orthogonal Frequency Division Multiplexing) signals. The metrics used to assess the efficiency of sensing methods are defined in the article. The paper also describes a model of the system and presents the simulation results. To conduct the research a hybrid detector was used, combining a fast detection method with a method ensuring high accuracy. Thanks to such a combination an increase in detection speed was obtained while maintaining the required reliability and sensitivity. The tests were carried out for the model of WiMAX signal and for the registered military radio signal.

Keywords: hybrid detector; sensing; WiMAX; OFDM; physical signal; noise uncertainty; sensing time.
