Abstract: Graph signal processing (GSP) studies signals that live on irregular data kernels described by graphs. One fundamental problem in GSP is sampling—from which subset of graph nodes to collect samples in order to reconstruct a… read more here.

DOI: 10.1109/tcsi.2022.3229690
Abstract: Expectation propagation (EP) achieves near-optimal performance for large-scale multiple-input multiple-output (L-MIMO) detection, however, at the expense of unaffordable matrix inversions. To tackle the issue, several low-complexity EP detectors have been proposed. However, they all fail… read more here.

DOI: 10.1109/tcsii.2020.3017381
Abstract: Expectation propagation (EP) achieves near-optimal performance for massive multiple-input multiple-output (MIMO) detection, however, at the cost of multiple expensive matrix inversions. An EP with approximation (EPA) algorithm has been introduced to address this issue, which… read more here.
