Optimal Wireless Streaming of Multi-Quality 360 VR Video by Exploiting Natural, Relative Smoothness-enabled and Transcoding-enabled Multicast Opportunities
Kaixuan Long, Ying Cui, Chencheng Ye +1
In this paper, we would like to investigate optimal wireless streaming of a multi-quality tiled 360 virtual reality (VR) video from a server to multiple users. To this end, we prop…
Neural Topic Modeling with Bidirectional Adversarial Training
Rui Wang, Xuemeng Hu, Deyu Zhou +4
Recent years have witnessed a surge of interests of using neural topic models for automatic topic extraction from text, since they avoid the complicated mathematical derivations fo…
Rate Splitting for Multi-Antenna Downlink: Precoder Design and Practical Implementation
Zheng Li, Chencheng Ye, Ying Cui +2
Rate splitting (RS) is a potentially powerful and flexible technique for multi-antenna downlink transmission. In this paper, we address several technical challenges towards its pra…
Analysis and Optimization of an Intelligent Reflecting Surface-assisted System with Interference
Yuhang Jia, Chencheng Ye, Ying Cui
In this paper, we study an intelligent reflecting surface (IRS)-assisted system where a multi-antenna base station (BS) serves a single-antenna user with the help of a multi-elemen…
Optimal Transmission of Multi-Quality Tiled 360 VR Video by Exploiting Multicast Opportunities
Kaixuan Long, Ying Cui, Chencheng Ye +1
In this paper, we would like to investigate fundamental impacts of multicast opportunities on efficient transmission of a 360 VR video to multiple users in the cases with and witho…
Stochastic Successive Convex Approximation for General Stochastic Optimization Problems
Chencheng Ye, Ying Cui
One key challenge for solving a general stochastic optimization problem with expectations in the objective and constraint functions using ordinary stochastic iterative methods lies…
Optimal Caching Designs for Perfect, Imperfect and Unknown File Popularity Distributions in Large-Scale Multi-Tier Wireless Networks
Chencheng Ye, Ying Cui, Yang Yang +1
Most existing caching solutions for wireless networks rest on an unrealistic assumption that the file popularity distribution is perfectly known. In this paper, we consider optimal…
Optimal Multi-Quality Multicast for 360 Virtual Reality Video
Kaixuan Long, Chencheng Ye, Ying Cui +1
A 360 virtual reality (VR) video, recording a scene of interest in every direction, provides VR users with immersive viewing experience. However, transmission of a 360 VR video whi…
