Short packet communication in IoT networks: performance analysis

Journal of Information and Telecommunication
In this paper, we investigated the block error rate (BLER) performance of a wireless powered communication network (WPCN) employing short packet communication (SPC). In this system, a source node harvests energy from a dedicated power beacon and utilizes

Enhancing the production of chlorophyll f in the cyanobacterium Synechocystis sp. PCC 6803

Physiologia Plantarum, Volume 177, Issue 2, March/April 2025.
Abstract One potential approach to improve the productivity of cyanobacteria and microalgae is to enhance photosynthetic efficiency by introducing far‐red absorbing pigment molecules (such as chlorophylls f and d) into the photosynthetic apparatus to expand the range of photosynthetically active radiation.

Association of MASLD Phenotypes With Liver Fibrosis in Hepatitis C: The Role of Cardiometabolic Risk Factors

Journal of Viral Hepatitis, Volume 32, Issue 2, February 2025.
ABSTRACT Steatotic liver disease is prevalent among people with hepatitis C virus (HCV). The new definition of metabolic dysfunction–associated steatotic liver disease (MASLD) emphasises the metabolic drivers of steatosis and recognises its frequent coexistence with other chronic liver diseases, including HCV.

5G‐coded fluid antenna multiple access over block fading channels

Electronics Letters, Volume 61, Issue 1, January/December 2025.
This letter investigates the use of 5G New Radio (NR) Modulation Coding Scheme (MCS) for FAMA systems to improve its connectivity over block fading channels. In particular, we propose an iterative decoding receiver with iterative interference covariance estimation, designed explicitly for slow fading channels.

Physical Layer Security Design for Polar Code Construction

Cryptography, 2022
In contrast to the network security that relies on upper-layer encryption for the confidentiality and authenticity of communications, physical layer security (PLS) exploits the uniqueness and randomness of the physical channel to encrypt information and ...

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.

Short Packet Communications for Relay Systems With Co-Channel Interference at Relay: Performance Analysis and Power Control

IEEE Access
In this paper, we evaluate short packet communication (SPC) for a cooperative system where one relay assists data transmission between one multi-antenna source and one single antenna destination with the presence of co-channel interference at the relay ...

Online fountain code with an improved caching mechanism

IET Communications, Volume 18, Issue 20, Page 1813-1825, December 2024.
By catching some selected encoded symbols discarded in the original online fountain codes and giving an optimal degree selection strategy of encoded symbols, the proposed online fountain code improves the receiving rules of the encoded symbols. The proposed online codes outperform the state‐of‐art online fountain codes in terms of overhead factors ...

Efficient LDPC Code Design based on Genetic Algorithm for IoT Applications

EAI Endorsed Transactions on Industrial Networks and Intelligent Systems
In this paper, we propose a low-density parity check (LDPC) code design scheme that improves the performance of the existing genetic algorithm-based LDPC scheme. In particular, we enhance the performance of the LDPC code by removing the girth-4 property
