Reconstruction with prior support information and non-Gaussian constraints

Xiaotong Liu, Yiyu Liang

In this study, we introduce a novel model, termed the Weighted Basis Pursuit Dequantization ( $ω$ -BPDQ $_{p}$ ), which incorporates prior support information by assigning weights on the…

A signal recovery guarantee with Restricted Isometry Property and Null Space Property for weighted $ℓ_{1}$ minimization

Xiaotong Liu, Yiyu Liang

Signal reconstruction is a crucial aspect of compressive sensing. In weighted cases, there are two common types of weights. In order to establish a unified framework for handling v…
