Abstract :
Spectrum sensing is a key of technology of cognitive radio. Based on differences between distribution of a modulated signal and a noise, in this paper, a spectrum sensing method is proposed. Simulations based on BPSK, QPSK, 16QAM and 64QAM show that our proposed method has low complexity of computation and good performance.
