Spectrum Sensing in Cognitive Radio: Use of Cyclo-
3.9
Cognitive radio allows unlicensed users to access licensed frequency bands through dynamic
spectrum access so as to reduce spectrum scarcity. This requires intelligent spectrum sensing
techniques like co-operative sensing which makes use of information from number of users. This
thesis investigates the use of cyclo-stationary detector and its simulation in MATLAB for
licensed user detection. Cyclo-stationary detector enables operation under low SNR conditions
and thus saves the need for consulting more number of users. Simulation results show that
implementing co-operative spectrum sensing help in better performance in terms of detect
