Spectrum sensing is an essential part of cognitive radio. Spectrum can be sensed by numerous algorithms. Energy based can easily detect presence of signal and cyclostationary based detection can easily detect signals at low SNR. The authors have collaborated the two algorithms resulting in a collaborative approach. In addition to that feature based detection has been used for calculating the probability of missed detection of TV signals at low SNR. In this paper, they have sensed the TV signals as well as the probability of missed detection for both are calculated.
