    Robust angle estimation for MIMO radar with the coexistence of mutual coupling and colored noise by Wang, Junxiang, Wang, Xianpeng, Xu, Dingjie, Bi, Guoan

    Published 2019
    “…This paper deals with joint estimation of direction-of-departure (DOD) and direction-of- arrival (DOA) in bistatic multiple-input multiple-output (MIMO) radar with the coexistence of unknown mutual coupling and spatial colored noise by developing a novel robust covariance tensor-based angle estimation method. In the proposed method, a third-order tensor is firstly formulated for capturing the multidimensional nature of the received data. …”

    Controllability of Markovian jump Boolean control networks by Meng, Min, Xiao, Gaoxi, Zhai, Chao, Li, Guoqi

    Published 2020
    “…In this paper, controllability of Markovian jump Boolean control networks (MJBCNs) is studied via semi-tensor product of matrices. First, based on the algebraic expression of the considered Boolean control networks, a necessary and sufficient condition for controllability is presented by iteration equations, which however may lead to high-dimensional matrices. …”
