On the Capacity of MISO Optical Intensity Channels With Per-Antenna Intensity Constraints
Ru-Han Chen, Longguang Li, Jian Zhang +2
This paper investigates the capacity of general multiple-input single-output (MISO) optical intensity channels (OICs) under per-antenna peak- and average-intensity constraints. We…
Decentralized Federated Learning: Balancing Communication and Computing Costs
Wei Liu, Li Chen, Wenyi Zhang
Decentralized stochastic gradient descent (SGD) is a driving engine for decentralized federated learning (DFL). The performance of decentralized SGD is jointly influenced by inter-…
A Rate-Distortion Framework for Characterizing Semantic Information
Jiakun Liu, Wenyi Zhang, H. Vincent Poor
A rate-distortion problem motivated by the consideration of semantic information is formulated and solved. The starting point is to model an information source as a pair consisting…
Generalized Nearest Neighbor Decoding for MIMO Channels with Imperfect Channel State Information
Shuqin Pang, Wenyi Zhang
Information transmission over a multiple-input-multiple-output (MIMO) fading channel with imperfect channel state information (CSI) is investigated, under a new receiver architectu…
Blind Diagnosis for Millimeter-wave Large-scale Antenna Systems
Rui Sun, Weidong Wang, Li Chen +2
Millimeter-wave (mmWave) communication systems rely on large-scale antenna arrays to combat large path-loss at mmWave band. Due to hardware characteristics and deployment environme…
Diagnosis of Intelligent Reflecting Surface in Millimeter-wave Communication Systems
Rui Sun, Weidong Wang, Li Chen +2
Intelligent reflecting surface (IRS) is a promising technology for enhancing wireless communication systems. It adaptively configures massive passive reflecting elements to control…
