Efficiently Computable Converses for Finite-Blocklength Communication

2022 IEEE International Symposium on Information Theory (ISIT), 2022
This paper presents a method for computing a finite-blocklength converse for the rate of fixed-length codes with feedback used on discrete memoryless channels (DMCs). The new converse is expressed in terms of a stochastic control problem whose solution can be efficiently computed using dynamic programming and Fourier methods.

BLER and Throughput Analysis of Power Beacon-Based Energy Harvesting UAV-Assisted NOMA Relay Systems for Short-Packet Communications

IEEE Access, 2023
In this paper, we analyze an unmanned aerial vehicle (UAV) that harvests energy from a power beacon to support the transmissions of finite blocklength packets from a source to two destinations using non-orthogonal multiple access (NOMA) scheme.

Lossy joint source-channel coding in the finite blocklength regime [PDF]

, 2012
This paper finds new tight finite-blocklength bounds for the best achievable lossy joint source-channel code rate, and demonstrates that joint source-channel code design brings considerable performance advantage over a separate one in the non-asymptotic ...

Slotted Aloha With Capture for OWC-Based IoT: Finite Block-Length Performance Analysis

IEEE Access, 2023
In this paper, we analyze the throughput and reliability of an indoor optical wireless communication (OWC)-based Internet of Things (IoT) system based on Slotted ALOHA (SA) where IoT devices exchange data with an access point (AP).

Data Compression With Low Distortion and Finite Blocklength [PDF]

IEEE Transactions on Information Theory, 2015
This paper considers lossy source coding of $n$-dimensional memoryless sources and shows an explicit approximation to the minimum source coding rate required to sustain the probability of exceeding distortion $d$ no greater than $ε$, which is simpler than known dispersion-based approximations.

Relaying with finite blocklength: Challenge vs. opportunity

2016 IEEE Sensor Array and Multichannel Signal Processing Workshop (SAM), 2016
In this paper, we study the performance of a system with multiple decode-and-forward (DF) relays under the finite blocklength (FBL) regime. We derive the FBL-Throughput under both perfect CSI and average CSI scenarios while the corresponding throughputs under an infinite blocklength assumption (IBL-throughput) are discussed as performance references ...

Short-Packet Downlink Transmission with Non-Orthogonal Multiple Access

, 2018
This work introduces downlink non-orthogonal multiple access (NOMA) into short-packet communications. NOMA has great potential to improve fairness and spectral efficiency with respect to orthogonal multiple access (OMA) for low-latency downlink ...
