Robust Sub-Meter Level Indoor Localization With a Single WiFi Access Point-Regression Versus Classification
Chenlu Xiang, Shunqing Zhang, Shugong Xu +3
Precise indoor localization is an increasingly demanding requirement for various emerging applications, like Virtual/Augmented reality and personalized advertising. Current indoor…
Majorization-Minimization Aided Hybrid Transceivers for MIMO Interference Channels
Shiqi Gong, Chengwen Xing, Vincent K. N. Lau +2
The potential of deploying large-scale antenna arrays in future wireless systems has stimulated extensive research on hybrid transceiver designs aiming to approximate the optimal f…
Parallel Stochastic Optimization Framework for Large-Scale Non-Convex Stochastic Problems
Naeimeh Omidvar, An Liu, Vincent Lau +2
In this paper, we consider the problem of stochastic optimization, where the objective function is in terms of the expectation of a (possibly non-convex) cost function that is para…
Closed-Form Delay-Optimal Computation Offloading in Mobile Edge Computing Systems
Xianling Meng, Wei Wang, Yitu Wang +2
Mobile edge computing (MEC) has recently emerged as a promising technology to release the tension between computation-intensive applications and resource-limited mobile terminals (…
Two-Timescale Hybrid Compression and Forward for Massive MIMO Aided C-RAN
An Liu, Xihan Chen, Wei Yu +2
We consider the uplink of a cloud radio access network (C-RAN), where massive MIMO remote radio heads (RRHs) serve as relays between users and a centralized baseband unit (BBU). Al…
Channel Estimation for WiFi Prototype Systems with Super-Resolution Image Recovery
Qi Shi, Yangyu Liu, Shunqing Zhang +3
Channel estimation is crucial for modern WiFi system and becomes more and more challenging with the growth of user throughput in multiple input multiple output configuration. Plent…
