Energy Efficient HARQ for Ultrareliability via Novel Outage Probability Bound and Geometric Programming
Kaiming Shen, Wei Yu, Xihan Chen +1
Hybrid automatic repeat 1 request (HARQ) is a key enabler for ultrareliable communications. This paper optimizes transmit power for the initial transmission and the subsequent retr…
Joint Design of Hybrid Beamforming and Reflection Coefficients in RIS-aided mmWave MIMO Systems
Renwang Li, Bei Guo, Meixia Tao +2
This paper considers a reconfigurable intelligent surface (RIS)-aided millimeter wave (mmWave) downlink communication system where hybrid analog-digital beamforming is employed at…
Exact Sparse Signal Recovery via Orthogonal Matching Pursuit with Prior Information
Jinming Wen, Wei Yu
The orthogonal matching pursuit (OMP) algorithm is a commonly used algorithm for recovering -sparse signals $\x\in \mathbb{R}^{n}$ from linear model $\y=\A\x$, where $\A\in \mat…
Optimization of Heterogeneous Coded Caching
Alexander Michael Daniel, Wei Yu
This paper aims to provide an optimization framework for coded caching that accounts for various heterogeneous aspects of practical systems. An optimization theoretic perspective o…
