SIGNAL DETECTION FOR SPECTRUM SENSING Spectrum sensing is a critical functionality in cognitive radio communications as it must be performed before allowing unlicensed users to access a vacant licensed band. Energy detector is also known as radiometer and it is most common method of spectrum sensing because of its low computational and implementation complexities. The coherent detector, also referred to as a matched filter, can improve detection performance if the primary transmitted signal, s, is deterministic and known a priori.
