On the Throughput of Channels that Wear Out

, 2018
This work investigates the fundamental limits of communication over a noisy discrete memoryless channel that wears out, in the sense of signal-dependent catastrophic failure.

Diversity versus Multiplexing at Finite Blocklength

, 2014
A finite blocklenth analysis of the diversity-multiplexing tradeoff is presented, based on nonasymptotic bounds on the maximum channel coding rate of multiple-antenna block-memoryless Rayleigh-fading channels.The bounds in this paper allow one to ...

Deep Transfer Learning-Based Performance Prediction of URLLC in Independent and Not Necessarily Identically Distributed Interference Networks

IEEE Access
In the rapidly evolving sixth-generation (6G) networks, achieving ultra-high reliability for short packets poses a crucial challenge for network designers as classical Shanon capacity bounds become obsolete.

Aerial Jamming Against Aerial Eavesdropping for UAV-Assisted Secure NOMA-URLLC Networks

IEEE Open Journal of the Communications Society
This paper investigates an unmanned aerial vehicle (UAV)-assisted non-orthogonal multiple access (NOMA) network, where a ground source (GS) communicates with a ground destination (GD) via a decode-and-forward (DF) aerial relay (AR), while an aerial ...

Distributed Storage for Data Security

, 2014
We study the secrecy of a distributed storage system for passwords. The encoder, Alice, observes a length-n password and describes it using two hints, which she then stores in different locations. The legitimate receiver, Bob, observes both hints.

Dynamic relay selection for AoI minimization in short packets based full-duplex energy harvesting-IoT networks

Journal of King Saud University: Computer and Information Sciences
The burgeoning demand for real-time status updates in the Internet of Things (IoT) underscores the importance of the age of information (AoI). While full-duplex (FD) relaying and energy harvesting (EH) are promising techniques for extending network ...

Robust design of reconfigurable intelligent surfaces for parameter estimation in MTC

EURASIP Journal on Wireless Communications and Networking
This paper introduces a reconfigurable intelligent surface (RIS) to support parameter estimation in machine-type communications (MTC). We focus on a network where single-antenna sensors transmit spatially correlated measurements to a multiple-antenna ...

Information Theoretic Analysis of PUF-Based Tamper Protection

Transactions on Cryptographic Hardware and Embedded Systems
PUFs enable physical tamper protection for high-assurance devices without needing a continuous power supply that is active over the entire lifetime of the device. Several methods for PUF-based tamper protection have been proposed together with practical
