Channel Estimation for Reconfigurable Intelligent Surface with a few Active Elements
Gyoseung Lee, Hyeongtaek Lee, Jaeky Oh +2
In this paper, a channel estimation technique for reconfigurable intelligent surface (RIS)-aided multi-user multiple-input single-output communication systems is proposed. By deplo…
Deep Learning Based NLOS Identification with Commodity WLAN Devices
Jeong-Sik Choi, Woong-Hee Lee, Jae-Hyun Lee +2
Identifying line-of-sight (LOS) and non-LOS (NLOS) channel conditions can improve the performance of many wireless applications, such as signal strength-based localization algorith…
Live Prefetching for Mobile Computation Offloading
Seung-Woo Ko, Kaibin Huang, Seong-Lyun Kim +1
The conventional designs of mobile computation offloading fetch user-specific data to the cloud prior to computing, called offline prefetching. However, this approach can potential…
BER-Based Physical Layer Security with Finite Codelength: Combining Strong Converse and Error Amplification
Il-Min Kim, Byoung-Hoon Kim, Joon Kui Ahn
A bit error rate (BER)-based physical layer security approach is proposed for finite blocklength. For secure communication in the sense of high BER, the information-theoretic stron…
