Abstract

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.
