A Scalable and Exact Relaxation for Densest -Subgraph via Error Bounds
Ya Liu, Junbin Liu, Wing-Kin Ma +1
Given an undirected graph and a size parameter , the Densest -Subgraph (DS) problem extracts the subgraph on vertices with the largest number of induced edges. While D…
Downlink MIMO Channel Estimation from Bits: Recoverability and Algorithm
Rajesh Shrestha, Mingjie Shao, Mingyi Hong +2
In frequency division duplex (FDD) massive MIMO systems, a major challenge lies in acquiring the downlink channel state information}\ (CSI) at the base station (BS) from limited fe…
Hyperspectral Unmixing Under Endmember Variability: A Variational Inference Framework
Yuening Li, Xiao Fu, Junbin Liu +1
This work proposes a variational inference (VI) framework for hyperspectral unmixing in the presence of endmember variability (HU-EV). An EV-accounted noisy linear mixture model (L…
One-Bit MIMO Detection: From Global Maximum-Likelihood Detector to Amplitude Retrieval Approach
Mingjie Shao, Wei-Kun Chen, Cheng-Yang Yu +2
As communication systems advance towards the future 6G era, the incorporation of large-scale antenna arrays in base stations (BSs) presents challenges such as increased hardware co…
