Deep reinforcement learning based computation offloading and resource allocation for MEC

TL;DR: This paper considers a multi-user MEC system, where multiple user equipments can perform computation offloading via wireless channels to an MEC server, and proposes RL-based optimization framework to tackle the resource allocation in wireless MEC.
Journal ArticleDOI

An ESPRIT-Based Approach for 2-D Localization of Incoherently Distributed Sources in Massive MIMO Systems

TL;DR: The analysis shows that the estimation performance of the proposed approach improves when the large-scale/massive MIMO systems are employed and the approximate Cramér-Rao bound ofThe proposed estimator for the 2-D localization is derived.
Journal ArticleDOI

Secrecy Transmit Beamforming for Heterogeneous Networks

TL;DR: This paper investigates secure communications in a two-tier downlink HetNet, which comprises one macrocell and several femtocells, and considers an orthogonal spectrum allocation strategy to eliminate co-channel interference.
Journal ArticleDOI

Multispectral optical metasurfaces enabled by achromatic phase transition.

TL;DR: A method to control the behaviors of different light waves through a metasurface which is able to generate achromatic geometric phase is proposed and may open a new door to the design of subminiature optical components and integrated optical system operating at multiple wavelengths.
Journal ArticleDOI

Secrecy Transmit Beamforming for Heterogeneous Networks

TL;DR: In this paper, the authors investigated secure communications in a two-tier downlink HetNet, which comprises one macrocell and several femtocells, and proposed two cooperative STBs which rely on the collaboration among the macrocell base station and the adjacent femtocell base stations (FBSs).
