Performance Evaluation of Short Packet Communications in NOMA VLC Systems With Imperfect CSI

open access: yesIEEE Access, 2022
In this paper, we analyze and evaluate the impacts of imperfect channel state information (CSI) of the short packet communication (SPC) in a non-orthogonal multiple access (NOMA) visible light communication (VLC) system.

Secrecy analysis of short-packet transmissions in ultra-reliable and low-latency communications

open access: yesEURASIP Journal on Wireless Communications and Networking, 2021
In this paper, we investigate the secrecy performance of short-packet transmissions in ultra-reliable and low-latency communications (URLLC). We consider the scenario where a multi-antenna source communicates with a single-antenna legitimate receiver ...

Operating ITS-G5 DSRC over Unlicensed Bands: A City-Scale Performance Evaluation [PDF]

open access: yes, 2019
Future Connected and Autonomous Vehicles (CAVs) will be equipped with a large set of sensors. The large amount of generated sensor data is expected to be exchanged with other CAVs and the road-side infrastructure.

Low-Latency Short-Packet Transmissions: Fixed Length or HARQ? [PDF]

open access: yes, 2018
We study short-packet communications, subject to latency and reliability constraints, under the premises of limited frequency diversity and no time diversity. The question addressed is whether, and when, hybrid automatic repeat request (HARQ) outperforms

On the Age of Information of Short-Packet Communications with Packet Management [PDF]

open access: yes2019 IEEE Global Communications Conference (GLOBECOM), 2019
In this paper, we consider a point-to-point wireless communication system. The source monitors a physical process and generates status update packets according to a Poisson process. The packets are transmitted to the destination by using finite blocklength coding to update the status (e.g., temperature, speed, position) of the monitored process.

MIMO-Based Physical Layer Evaluation on IEEE 802.11bd

open access: yesIEEE Access, 2023
To enable vehicle-to-everything (V2X) communications, both the dedicated short-range communications (DSRC) and the cellular V2X (C-V2X) involved in the radio access technologies (RATs) are experiencing extensive development to support advanced vehicular ...

A Cross-Layer Approach for Minimizing Interference and Latency of Medium Access in Wireless Sensor Networks [PDF]

open access: yes, 2010
In low power wireless sensor networks, MAC protocols usually employ periodic sleep/wake schedule to reduce idle listening time. Even though this mechanism is simple and efficient, it results in high end-to-end latency and low throughput.
