Hybrid FSK-PSK Waveform Optimization for Radar Based on Alternating Direction Method of Multiplier (ADMM) [PDF]
Sensors, 2021 In this paper, a new radar signal modulated with a hybrid of the frequency shift keying (FSK) and the phase shift keying (PSK) signal—i.e., the FSK-PSK signal—is studied.

Alternating direction method of multiplier for tomography with nonlocal regularizers. [PDF]
IEEE Trans Med Imaging, 2014 The ordered subset expectation maximization (OSEM) algorithm approximates the gradient of a likelihood function using a subset of projections instead of using all projections so that fast image reconstruction is possible for emission and transmission tomography such as SPECT, PET, and CT.

An Alternating Direction Multiplier Method for the Inversion of FDEM Data [PDF]
Journal of Scientific ComputingAbstractIn this paper, we focus on the numerical solution of nonlinear inverse problems in applied geophysics. Our aim is to reconstruct the structure of the soil, i.e., either its electrical conductivity or the magnetic permeability distribution, by inverting frequency domain electromagnetic data.

Extrapolation Accelerated Linear Alternating Direction Multiplier Method for Split Feasibility Problems and Its Global Convergence [PDF]
Jisuanji kexue, 2023 This paper deals with a linear alternating direction multiplier method (ADMM) for Split feasibility problems (SFP).More specifically,the SFP has been formulated as a separable convex minimization problem with linear constraints,and then extrapolation ...

An Adaptive Alternating Direction Method of Multipliers
Journal of Optimization Theory and Applications, 2022 AbstractThe alternating direction method of multipliers (ADMM) is a powerful splitting algorithm for linearly constrained convex optimization problems. In view of its popularity and applicability, a growing attention is drawn toward the ADMM in nonconvex settings.

Truncated Fractional-Order Total Variation for Image Denoising under Cauchy Noise
Axioms, 2022 In recent years, the fractional-order derivative has achieved great success in removing Gaussian noise, impulsive noise, multiplicative noise and so on, but few works have been conducted to remove Cauchy noise. In this paper, we propose a novel nonconvex
