Expectation Consistent Plug-and-Play for MRI
Saurav K Shastri, Rizwan Ahmad, Christopher A Metzler +1
For image recovery problems, plug-and-play (PnP) methods have been developed that replace the proximal step in an optimization algorithm with a call to an application-specific deno…
A Simple Derivation of AMP and its State Evolution via First-Order Cancellation
Philip Schniter
We consider the linear regression problem, where the goal is to recover the vector from measurements $\boldsymbol{y}=\boldsymbol{A}\boldsymbol{x}+\b…
Multi-User Detection Based on Expectation Propagation for the Non-Coherent SIMO Multiple Access Channel
Khac-Hoang Ngo, Maxime Guillaud, Alexis Decurninge +2
We consider the non-coherent single-input multiple-output (SIMO) multiple access channel with general signaling under spatially correlated Rayleigh block fading. We propose a novel…
Bilinear Recovery using Adaptive Vector-AMP
Subrata Sarkar, Alyson K. Fletcher, Sundeep Rangan +1
We consider the problem of jointly recovering the vector and the matrix from noisy measurements $\boldsymbol{Y} = \boldsymbol{A}(\boldsymbol{b})\b…
Joint Channel-Estimation/Decoding with Frequency-Selective Channels and Few-Bit ADCs
Peng Sun, Zhongyong Wang, Robert W. Heath +1
We propose a fast and near-optimal approach to joint channel-estimation, equalization, and decoding of coded single-carrier (SC) transmissions over frequency-selective channels wit…
An Expectation-Maximization Approach to Tuning Generalized Vector Approximate Message Passing
Christopher A. Metzler, Philip Schniter, Richard G. Baraniuk
Generalized Vector Approximate Message Passing (GVAMP) is an efficient iterative algorithm for approximately minimum-mean-squared-error estimation of a random vector $\mathbf{x}\si…
