Interpolation-Based Direction-of-Arrival Estimation for Coprime Arrays via Covariance Matrix Fitting
IEEE Access, 2020 Coprime arrays can highly increase degree-of-freedom (DOF) by exploiting the equivalent virtual signal. However, since the corresponding virtual array constructed by the coprime array is always a non-uniform linear array (non-ULA), most existing ...

A RIS‐Based Single‐Channel Direction‐of‐Arrival Estimation Method for Communication Signals
IET Communications, Volume 19, Issue 1, January/December 2025.This paper proposes a reconfigurable intelligent surface (RIS)‐based single‐channel direction‐of‐arrival (DOA) estimation method for communication signals. Our method, which incorporates RIS, extended time intervals, atomic norm minimization (‐alternating direction method of multipliers, and mutual incoherence property, addresses the two main problems:

Amortization does not enhance the max-Rains information of a quantum channel
New Journal of Physics, 2018 Given an entanglement measure E , the entanglement of a quantum channel is defined as the largest amount of entanglement E that can be generated from the channel, if the sender and receiver are not allowed to share a quantum state before using the ...

SDP‐based approach to monocular reconstruction of inextensible surfaces
IET Computer Vision, 2017 This study addresses the problem of monocular reconstruction of surfaces that deform isometrically, using points tracked in a single image. To tackle this problem, a flat three‐dimensional (3D) shape of the surface and its image are used as template ...
