| Abstract: | In order to mine the spectrum resources on radio and TV ultra high frequency (UHF), the paper is based on the research about cognitive radio, and compares with the advantage and disadvantage of the three common spectrum sensing methods based on the transmitter under non-cooperation pattern. The algorithm of cyclostationary feature detection is mainly introduced. The simulation of spectrum sensing on MATLAB is finished, aiming at Chinese mobile multimedia broadcast (CMMB). Effect demonstration is achieved on GUI. |
