The challenges associated with the determination of detection threshold due to uncertainty were addressed in this paper. The technique of Cooperative Sensing Spectrum (CSS) was used to model the functional subsystems that made up the cognitive radio system. The model developed utilizes channel center frequencies. Also, implemented and threshold actualized for the presence/absence of PU based on false alarm and detection decisions. The innovative approach employed the use of FLA (Fuzzy Logic Algorithm) for the improvement of the detection threshold.
