Statistical Recovery of Simultaneously Sparse Time-Varying Signals from Multiple Measurement Vectors
Jun Won Choi, Byonghyo Shim
In this paper, we propose a new sparse signal recovery algorithm, referred to as sparse Kalman tree search (sKTS), that provides a robust reconstruction of the sparse vector when t…

Greedy Sparse Signal Recovery with Tree Pruning
Jaeseok Lee, Suhyuk Kwon, Jun Won Choi +1
Recently, greedy algorithm has received much attention as a cost-effective means to reconstruct the sparse signals from compressed measurements. Much of previous work has focused o…

Antenna Grouping based Feedback Compression for FDD-based Massive MIMO Systems
Byungju Lee, Junil Choi, Ji-yun Seol +2
Recent works on massive multiple-input multiple-output (MIMO) have shown that a potential breakthrough in capacity gains can be achieved by deploying a very large number of antenna…
