Investigation on hybrid automatic repeat request (HARQ) design for NOMA with SU-MIMO

2015 IEEE 26th Annual International Symposium on Personal, Indoor, and Mobile Radio Communications (PIMRC), 2015
Non-orthogonal multiple access (NOMA) utilizing power domain and advanced receiver has been considered as a very promising candidate radio access technology for future wireless communication systems. Hybrid automatic repeat request (HARQ), as an indispensable part of link adaptation, plays a very important role in reliable high speed packet data ...

A Design of Hybrid Automatic Repeat Request Scheme Based on Systematic Polar Codes

2020 IEEE 10th International Conference on Electronics Information and Emergency Communication (ICEIEC), 2020
Hybrid Automatic Repeat reQuest (HARQ) technology which is widely used in modern communication systems is a combination of ARQ technology and Forward Error Control (FEC) technology. Finding a high-performance FEC coding scheme has a great influence on the performance of HARQ system.

Resource allocation in 5G network using Orthogonal Frequency Division Multiplexing‐Hybrid Automatic Repeat Request

International Journal of Communication Systems, 2022
SummaryFading, interference, and collisions cause unpredictable data loss in a wireless channel. In the recent past, the use of polar codes for error detection and correction scaled downed the data error rate considerably. With the introduction of 5G mobile network, minimizing the data loss and enhancing the performance becomes imperative.

A Hybrid Automatic Repeat reQuest Scheme Based on Maximum Distance Separable Codes

2017
For communication systems, a good error control technology is expected to get higher data transmission rate without reducing the quality of service. This paper presents a Hybrid Automatic Repeat reQuest (HARQ) scheme based on Maximum Distance Separable (MDS) codes to improve the ability of error correction. We divide the file into several segments, i.e.

A 100Gbps data link layer with a frame segmentation and hybrid automatic repeat request

2015 Science and Information Conference (SAI), 2015
This paper presents simulation results of the data link layer for 100Gbps wireless communication. A frame aggregation and segmentation, forward error correction codes, and a hybrid automatic repeat request scheme are in the scope. The frame segmentation suffers from the acknowledge frame length currently, and this aspect has to be improved.

Asymmetric rate compatible turbo codes in hybrid automatic repeat request schemes

IEE Proceedings - Communications, 2006
The authors present asymmetric turbo hybrid automatic-repeat-request (ATH-ARQ) schemes that employ component code selection and asymmetric rate compatible punctured turbo codes (ARCPT) for enhanced performance in fading channels. The paper also presents a novel low-rate ARCPT encoder structure.

Parallel Concatenation Codes with Polar Component Codes for Incremental Redundancy Hybrid Automatic Repeat reQuest Functionality

2020 International Wireless Communications and Mobile Computing (IWCMC), 2020
This article develops a novel method for construction of parallel concatenation codes with Polar Codes as component code. These parallel concatenation codes are similar to the Turbo codes in construction. Actually, it is a combination of the idea of parallel concatenation codes and the coding essential of the Polar codes.

Performance evaluations of hybrid automatic repeat request schemes for a data communication system

Electronics and Communications in Japan (Part III: Fundamental Electronic Science), 1996
AbstractIt is generally impossible to avoid occurrences of errors of the data transmission because of the disturbing factors such as disconnections, noises or distortions in a communication line. Therefore, the error‐control procedure is indispensable to trnnsmit high‐quality data and its various techinques have been considered from the viewpoints of ...

Scoped hybrid automatic repeat reQuest with forward error correction (SHARQFEC)

Proceedings of the ACM SIGCOMM '98 conference on Applications, technologies, architectures, and protocols for computer communication, 1998
Reliable multicast protocols scale only as well as their ability to localize traffic. This is true for repair requests, repairs, and the session traffic that enables receivers to suppress extraneous requests and repairs. We propose a new reliable multicast traffic localization technique called Scoped Hybrid Automatic Repeat reQuest with Forward Error ...
