Abstract

cognitive radio
spectrum sensing , GLRT detector, ED detector , Maximum likelihood estimation, LO detector.
The timing misalignment issue should be considered for spectrum sensing in cognitive radio (CR) systems due to the random arrival of primary users, such as CR-based femtocell networks. To deal withthis issue, two approaches Bayesian and generalized likelihood ratio test (GLRT) detectors are dealt in this paper.To design a low-complexity energy detector (ED), this work proposes an ED scheme based on the GLRT algorithm. As a result, maximum- likelihood estimation for the timing misalignment is devised, and the performance of the proposed scheme is analyzed. The results show that the proposed GLRT detector features a low-complexity and satisfactory performance. In this paper, we investigate a Locally Optimum (LO) detection of random signals under a weakly correlated noise model over fading channels. Therefore, we try to come up with an LO detection technique with comparable complexity to energy detection for correlated noise environments.
