WebJun 12, 2024 · To solve the problem of noise power uncertainty, generalized likelihood ratio test based on polarization vector (GLRT-PV) is proposed in . GLRT-PV is a blind sensing method which summarizes the observed samples of polarization vector as the polarization state information. Although GLRT-PV process the constant false alarm rate (CFAR) in … Webfeature as one of the parameters using GLRT method. During the preparation of this paper, we notice that [22] has also derived several GLRT-based algorithms using the latest results from the finite-sample optimality of GLRT [23]. [22] has shown interesting results by introducing prior distribution of unknown parameters to obtain better ...
