A Hybrid Automatic Repeat Request (HARQ) with Turbo Codes in OFDM System

2010 International Conference on Computational Intelligence and Software Engineering, 2010
In this paper a hybrid automatic repeat request (HARQ) with turbo codes in OFDM system, and the differences hybrid ARQ methods designed for Turbo-coded transmissions on OFDM are presented. Two kinds of modified methods, one without ARQ and the other one are with HARQ: HARQ type-I and HARQ type-II.

Performance analysis of a cross-layered incremental redundancy hybrid automatic repeat request (CL IR-HARQ) mechanism

Ad Hoc Networks, 2014
The performance of Hybrid Automatic Repeat reQuest (HARQ) in wireless networks has been extensively studied in recent years. Most of the HARQ performance results reported in the literature have been based on cross-layer techniques making use of Media Access Control (MAC) and physical layer information.

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 ...

Variable-length coding incremental redundancy hybrid automatic repeat reQuest (HARQ) over fading channels

2015
In order to overcome the adverse effects of fading in wireless telecommunication channels, using a combination of error correcting codes and repeat requests has proven to be a practical solution. Such a combination is indeed offered in Hybrid Automatic Repeat reQuest (HARQ) where retransmissions of encoded bits from the same message packet increase ...
