Peak-to-average power ratio of good codes for Gaussian channel [PDF]

open access: yes, 2014
Consider a problem of forward error-correction for the additive white Gaussian noise (AWGN) channel. For finite blocklength codes the backoff from the channel capacity is inversely proportional to the square root of the blocklength.

Joint Optimization for Secure and Reliable Communications in Finite Blocklength Regime

open access: yesIEEE Transactions on Wireless Communications, 2023
To realize ultra-reliable low latency communications with high spectral efficiency and security, we investigate a joint optimization problem for downlink communications with multiple users and eavesdroppers in the finite blocklength (FBL) regime. We formulate a multi-objective optimization problem to maximize a sum secrecy rate by developing a secure ...

Ultra Reliable Communication via Optimum Power Allocation for HARQ Retransmission Schemes

open access: yesIEEE Access, 2020
In this work, we develop low complexity, optimal power allocation algorithms that would allow ultra reliable operation at any outage probability target with minimum power consumption in the finite blocklength regime by utilizing Karush-Kuhn-Tucker (KKT ...

Reliability-Oriented Design Framework in NOMA-Assisted Mobile Edge Computing

open access: yesIEEE Access, 2022
In this paper, we consider mission-critical task offloading in the non-orthogonal multiple access (NOMA)-assisted mobile edge computing (MEC) networks, where local information collected from multiple local devices are processed at the MEC node.

Rate Optimization for RIS-Aided mMTC Networks in the Finite Blocklength Regime

open access: yesIEEE Communications Letters, 2023
Reconfigurable intelligent surfaces (RISs) have become a promising candidate for the development of future mobile systems. In the context of massive machine-type communications (mMTC), a RIS can be used to support the transmission from a group of sensors to a collector node.

Low-Complexity Joint Channel Estimation and List Decoding of Short Codes [PDF]

open access: yes, 2019
A pilot-assisted transmission (PAT) scheme is proposed for short blocklengths, where the pilots are used only to derive an initial channel estimate for the list construction step.

When Asymmetry Helps: Joint Power and Blocklength Optimization for Non-Orthogonal Multiple Access in Downlink Communications

open access: yesIEEE Open Journal of the Communications Society
This paper investigates downlink non-orthogonal multiple access (NOMA) in short-packet communications, specifically focusing on a scenario where an Access Point (AP) serves two users with varying channel conditions.
