Abstract : Large numbers of spectrum sensing techniques have been introduced to detect the presence of primary users. Though each technique has its own advantages and disadvantages, the disadvantages associated with one leads to the development of the others. A two stage detector for spectrum sensing can be used to overcome the limitations of a single stage detection technique and to combine the advantages offered by the individual methods. However, a two stage spectrum sensing technique increases the time taken for sensing a spectrum. In this paper, a novel method is proposed that effectively decreases the time taken for sensing the spectrum whereas meeting the required detection capabilities. Simulation results have been used to show that the proposed method leads to larger savings in time compared to the already available two stage detection method for spectrum sensing.
