Reweighted l1-norm Penalized LMS for Sparse Channel Estimation and Its Analysis
Omid Taheri, Sergiy A. Vorobyov
A new reweighted l1-norm penalized least mean square (LMS) algorithm for sparse channel estimation is proposed and studied in this paper. Since standard LMS algorithm does not take…

Permutation Meets Parallel Compressed Sensing: How to Relax Restricted Isometry Property for 2D Sparse Signals
Hao Fang, Sergiy A. Vorobyov, Hai Jiang +1
Traditional compressed sensing considers sampling a 1D signal. For a multidimensional signal, if reshaped into a vector, the required size of the sensing matrix becomes dramaticall…

Segmented compressed sampling for analog-to-information conversion: Method and performance analysis
Omid Taheri, Sergiy A. Vorobyov
A new segmented compressed sampling method for analog-to-information conversion (AIC) is proposed. An analog signal measured by a number of parallel branches of mixers and integrat…
