Transition‐Aware Q‐Learning for Robust Tracking in Networked Control Systems with Fading Channels: Application to Leader−Follower Vehicle Control

IET Control Theory &Applications, Volume 20, Issue 1, January/December 2026.
Maintaining reliable tracking control in networked control systems over fading wireless channels is difficult due to the stochastic and time‐correlated nature of wireless links. This work proposes a transition‐aware Q‐learning (TA‐QL) method that learns robust control policies directly from networked data without requiring explicit models, while ...

Performance of NOMA systems with HARQ-CC in finite blocklength [PDF]

, 2019
With the advent of new use-cases requiring high reliability and low-latency, transmission with finite blocklength becomes inevitable to reduce latency. In contrast to classical information-theoretic principles, the use of finite blocklength results in a ...

Delay-Sensitive NOMA-HARQ for Short Packet Communications

Entropy, 2021
This paper investigates the two-user uplink non-orthogonal multiple access (NOMA) paired with the hybrid automatic repeat request (HARQ) in the finite blocklength regime, where the target latency of each user is the priority. To limit the packet delivery

Finite-blocklength Fluid Antenna Systems

CoRR
This paper investigates fluid antenna systems (FASs) subject to finite-blocklength (FBL) constraints, motivated by the strict reliability-latency and ultra-massive connectivity requirements of future wireless networks. While FAS performance has been widely studied in the asymptotic regime, its behavior under FBL remains largely unexplored.

Block Error Rate Minimization of Downlink MIMO‐NOMA With Finite Blocklength

Electronics Letters, Volume 61, Issue 1, January/December 2025.
This paper investigates the downlink multiple‐input multiple‐output (MIMO)‐non‐orthogonal multiple access (NOMA) transmission with finite blocklength (FBL). Our aim is to achieve the minimum average block error rate (BLER) by proposing an efficient power, rate, and blocklength allocation scheme.

Energy‐Efficient UAV‐Assisted Covert Communication in WSN With Finite Blocklength

Electronics Letters, Volume 61, Issue 1, January/December 2025.
This paper proposes a jointly optimizing UAV trajectory and wake‐up scheduling method (JOUTWUSM) for finite blocklength covert communication in wireless sensor networks. By optimizing the UAV's trajectory and sensor node wake‐up scheduling, the method effectively balances energy efficiency and communication reliability under finite blocklength ...

Block-fading channels with delayed CSIT at finite blocklength [PDF]

2014 IEEE International Symposium on Information Theory, 2014
In many wireless systems, the channel state information at the transmitter (CSIT) can not be learned until after a transmission has taken place and is thereby outdated. In this paper, we study the benefits of delayed CSIT on a block-fading channel at finite blocklength.

Flexible Design of Finite Blocklength Wiretap Codes by Autoencoders

, 2019
With an increasing number of wireless devices, the risk of being eavesdropped increases as well. From information theory, it is well known that wiretap codes can asymptotically achieve vanishing decoding error probability at the legitimate receiver while

Ensuring Data Freshness for MU-MISO Networks in Finite Blocklength Regime

, 2022
In this paper, we analyze the effect of the finite blocklength on the data freshness in multi-user multiple-input single-output (MISO) networks, where a base station (BS) equipped with multiple antennas serves users.
