In this paper, cumulant based direction of arrival (DOA) estimation using multiple invariances is proposed which results in Multiple Invariance Cumulant ESPRIT (MICE) algorithm. In all previous formulations of cumulant based ESPRIT, only one invariance is exploited for DOA estimation. The cumulant matrix (if chosen properly) inherits the multiple invariance property if multiple displacement invariances...
In this paper, we propose a new 2-dimensional beamspace matrix pencil (2D BMP) method for direction of arrival (DOA) estimation of plane wave signals using a uniform rectangular array (URA). Based on some a priori information about DOA, the proposed method transforms the complex signal subspace in 2D matrix pencil (2D MP) method [Y. Hua, Estimating two-dimensional frequencies by matrix enhancement...
The Matrix Pencil (MP) method is a direct data domain method that can be used to estimate direction of arrivals (DOA) of coherent or non-coherent signals from a single snapshot of a uniform linear array (ULA). Recently, many variants of MP method have been proposed including Unitary Matrix Pencil (UMP), Single invariance Beamspace Matrix Pencil (SBMP) and Multiple invariance Beamspace Matrix Pencil(MBMP)...
