Abstract :
By applying Anderson-Darling test in statistics into spectrum sensing, this paper gives a new sensing of existence of unknown signals. Both theoretical analysis and simulations show that the proposed sensing method has much higher probability of detection than energy detector-based sensing, especially in a low SNR region and a case with a small sampling number.
