Eckehard Steinbach,Matti Strese,Mohamad Eid,Xun Liu,Amit Bhardwaj,Qian Liu,Mohammad Al-Ja'afreh,Toktam Mahmoodi,Rania Hassen,Abdulmotaleb El Saddik,Oliver Holland +10 more
TL;DR: In this article, the authors present the fundamentals and state of the art in haptic codec design for the Tactile Internet and discuss how limitations of the human haptic perception system can be exploited for efficient perceptual coding of kinesthetic and tactile information.
Journal ArticleDOI
Utility Aware Offloading for Mobile-Edge Computing
TL;DR: This study investigates the problem of finding an optimal offloading scheme in which the objective of optimization aims to maximize the system utility for leveraging between throughput and fairness and provides an increment-based greedy approximation algorithm with 1 + 1/e-1 ratio.
Journal ArticleDOI
Dynamic Hybrid Beamforming With Low-Resolution PSs for Wideband mmWave MIMO-OFDM Systems
TL;DR: This paper introduces a novel hybrid beamforming architecture with dynamic antenna subarrays and hardware-efficient low-resolution phase shifters (PSs) for a wideband mmWave MIMO orthogonal frequency division multiplexing (MIMO-OFDM) system and jointly design the hybrid precoder and combiner to maximize the average spectral efficiency.
Journal ArticleDOI
Disrupting MIMO Communications With Optimal Jamming Signal Design
TL;DR: An optimal jamming signal design is presented, which can maximally disrupt the MIMO transmission when the transceiver adopts an anti-jamming mechanism, and signal-to- Jamming-plus-noise ratio (SJNR) at the receiver is used as the anti- jamming reliability metric of the legitimate MIMo transmission.
