Cognitive Radio (CR) enables Dynamic Spectrum Access (DSA) and opportunistic transmission of the Secondary User (SU) in authorized primary frequency bands, which is of great promise to promote the efficiency of frequency utilization and hence alleviate the scarcity of spectrum resources A Cognitive Radio (CR) is a transceiver which automatically detects available channels in wireless spectrum and accordingly changes its transmission or reception parameters. In this paper, it proposes combined technique for sensing the spectrum for cognitive radios. Here, the authors make use of the main two sensing techniques called ED (Energy Detection) method and MF (Matched Filter) method to simultaneously sense the wireless environment and produce better detection performance.
