| Abstract: | A new spectrum sensing algorithm for the cognitive radio system based on energy detection named the joint filters spectrum sensing algorithm using filter banks is given. The excellence of the new algorithm is proved based on the signal-to-noise ratio analysis. The detection probability and the false-alarm probability are simulated and compared with those of the classical energy sensing algorithms based on filter banks. |
