Age of Information for Short-Packet Covert Communication
IEEE Wireless Communications Letters, 2021In this letter, we develop a new framework to jointly characterize covertness and timeliness of short-packet communications, in which a new metric named covert age of information (CAoI) is first proposed and then a closed-form expression for the average CAoI is derived.

Performance analysis of short-packet communications with incremental relaying
Computer Communications, 2021Abstract In the fifth generation (5G) cellular system, short-packet communication is a key enabler to support critical applications, i.e., ultra-reliable low-latency communications (URLLCs), where finite block-length codewords are adopted. However, the short-packet communication suffers from a higher decoding error rate and has a lower transmission ...

Performance Analysis of Short Packet Communications With Multiple Eavesdroppers
IEEE Transactions on Communications, 2022This paper studies the performance of short packet communications in the presence of multiple eavesdroppers. We start our investigation by examining the fading wiretap channel, where the communication is overheard by multiple non-colluding single antenna eavesdroppers.

Coding Performance Modeling for Short-Packet Communications
2019 53rd Asilomar Conference on Signals, Systems, and Computers, 2019In this paper, an analytic model is developed to predict the performance of modern error correcting codes and modulation schemes over wireless channels with non-ideal channel estimation. The model is based on recent advances in finite- blocklength information theory, which provide accurate performance metrics for the transmission of short packets.

Delay-Tolerant Autonomous Transmissions for Short Packet Communications
2016 IEEE Globecom Workshops (GC Wkshps), 2016The cellular network evolution has generally focused on improving system and edge user throughput while reducing latency. Recently, a new class of service involving the communication of short packets has emerged wherein scale, coverage, reliability, and energy efficiency has greater importance than the rate or latency at which the information is ...
