Abstract |
We propose an effective spectrum sensing method which exploits the combination of comb filter and autocorrelation function in a parallel form. In our proposed method, the primary user information is not required for spectrum sensing, but the noise variance is used, which corresponds to a semi blind one. A comprehensive evaluation by simulations shows that the proposed method is useful for low signal-to-noise ratio (SNR) cases.
