Channel Estimation and Hybrid Precoding for Frequency Selective Multiuser mmWave MIMO Systems
J. P. González-Coma, J. Rodríguez-Fernández, N. González-Prelcic +2
Configuring the hybrid precoders and combiners in a millimeter wave (mmWave) multiuser (MU) multiple-input multiple-output (MIMO) system is challenging in frequency selective chann…
Joint Band Assignment and Beam Management using Hierarchical Reinforcement Learning for Multi-Band Communication
Dohyun Kim, Miguel R. Castellanos, Robert W. Heath
Multi-band operation in wireless networks can improve data rates by leveraging the benefits of propagation in different frequency ranges. Distinctive beam management procedures in…
From Multilayer Perceptron to GPT: A Reflection on Deep Learning Research for Wireless Physical Layer
Mohamed Akrout, Amine Mezghani, Ekram Hossain +2
Most research studies on deep learning (DL) applied to the physical layer of wireless communication do not put forward the critical role of the accuracy-generalization trade-off in…
Sparse RF Lens Antenna Array Design for AoA Estimation in Wideband Systems: Placement Optimization and Performance Analysis
Joo-Hyun Jo, Jae-Nam Shim, Chan-Byoung Chae +2
In this paper, we propose a novel architecture for a lens antenna array (LAA) designed to work with a small number of antennas and enable angle-of-arrival (AoA) estimation for adva…
Hierarchical Codebook Design with Dynamic Metasurface Antennas for Energy-Efficient Arrays
Joseph Carlson, Miguel R. Castellanos, Robert W. Heath
Dynamic metasurface antennas (DMA) provide a solution to form compact, cost-effective, energy-efficient multiple-input-multiple output (MIMO) arrays. In this paper, we implement a…
Online variable-length source coding for minimum bitrate LQG control
Travis C. Cuvelier, Takashi Tanaka, Robert W. Heath
We propose an adaptive coding approach to achieve linear-quadratic-Gaussian (LQG) control with near-minimum bitrate prefix-free feedback. Our approach combines a recent analysis of…
