Two-Dimensional DOA Estimation for Coherently Distributed Sources with Symmetric Properties in Crossed Arrays
In this paper, a novel algorithm is proposed for the two-dimensional (2D) central direction-of-arrival (DOA) estimation of coherently distributed (CD) sources. Specifically, we focus on a centro-symmetric crossed array consisting of two uniform linear arrays (ULAs). Unlike the conventional low-complexity methods using the one-order Taylor series approximation to obtain the approximate rotationa...
متن کاملNovel two-dimensional DOA estimation with L-shaped array
Two-dimensional (2D) direction-of-arrival (DOA) estimation has played an important role in array signal processing. In this article, we address a problem of bind 2D-DOA estimation with L-shaped array. This article links the 2D-DOA estimation problem to the trilinear model. To exploit this link, we derive a trilinear decomposition-based 2D-DOA estimation algorithm in L-shaped array. Without spec...
متن کاملWiring Space Estimation in Two-Dimensional Arrays
We propose a new global routing area estimation approach for high-performance VLSI and MCMs. The objective is to route nets with minimum density of global cells, producing a four-bend routing for each two-terminal net. A solution to this problem can also be used for quick estimation of necessary wiring space (for standard cell array designs) and difficulty of routing (for gate array designs) in...
متن کاملDecoupled Nominal 2-D Direction-of -Arrival Estimation Algorithm for Coherently Distributed Source
A computationally efficient method for nominal 2-D (azimuth and elevation) direction-of-arrival (DOA) estimation of coherently distributed source impinging on the far field is presented. Since the coherently distributed source is characterized by four parameters, the nominal azimuth DOA, angular spread of the nominal azimuth DOA, the nominal elevation DOA, and angular spread of the nominal elev...
متن کاملA Low-Complexity Method for Two-Dimensional Direction-of-Arrival Estimation Using an L-Shaped Array
In this paper, a new low-complexity method for two-dimensional (2D) direction-of-arrival (DOA) estimation is proposed. Based on a cross-correlation matrix formed from the L-shaped array, the proposed algorithm obtains the automatic pairing elevation and azimuth angles without eigendecomposition, which can avoid high computational cost. In addition, the cross-correlation matrix eliminates the ef...
