Abstract :
This article introduces two typical means of spectrum sensing in CR: energy detection and cyclostationary detection. Two methods are used to verify the feasibility and detect authorized user in CR-OFDM system. It illustrates that how to choose parameters when detect the OFDM signals by MATLAB. It compares the superiorities and deficiencies of the two ways, then puts forward the improved solution.
