An Information Theoretic Study for Noisy Compressed Sensing With Joint Sparsity Model-2
Sangjun Park, Nam Yul Yu, Heung-No Lee
In this paper, we study a support set reconstruction problem in which the signals of interest are jointly sparse with a common support set, and sampled by joint sparsity model-2 (J…
Bayesian Hypothesis Test using Nonparametric Belief Propagation for Noisy Sparse Recovery
Jaewook Kang, Heung-No Lee, Kiseon Kim
This paper proposes a low-computational Bayesian algorithm for noisy sparse recovery (NSR), called BHT-BP. In this framework, we consider an LDPC-like measurement matrices which ha…
Restricted Isometry Random Variables: Probability Distributions, RIC Prediction and Phase Transition Analysis for Gaussian Encoders
Oliver James, Heung-No Lee
In this paper, we aim to generalize the notion of restricted isometry constant (RIC) in compressive sensing (CS) to restricted isometry random variable (RIV). Associated with a det…
Bernoulli-Gaussian Approximate Message-Passing Algorithm for Compressed Sensing with 1D-Finite-Difference Sparsity
Jaewook Kang, Hyoyoung Jung, Heung-No Lee +1
This paper proposes a fast approximate message-passing (AMP) algorithm for solving compressed sensing (CS) recovery problems with 1D-finite-difference sparsity in term of MMSE esti…
Concise Probability Distributions of Eigenvalues of Real-Valued Wishart Matrices
Oliver James, Heung-No Lee
In this paper, we consider the problem of deriving new eigenvalue distributions of real-valued Wishart matrices that arises in many scientific and engineering applications. The dis…
Circular Sphere Decoding: A Low Complexity Detection for MIMO Systems with General Two-dimensional Signal Constellations
Hwanchol Jang, Saeid Nooshabadi, Kiseon Kim +1
We propose a low complexity complex valued Sphere Decoding (CV-SD) algorithm, referred to as Circular Sphere Decoding (CSD) which is applicable to multiple-input multiple-output (M…
