Age of Incorrect Information With Hybrid ARQ Under a Resource Constraint for N-Ary Symmetric Markov Sources

IEEE Transactions on Networking, 2023
The Age of Incorrect Information (AoII) is a recently proposed metric for real-time remote monitoring systems. In particular, AoII measures the time the information at the monitor is incorrect, weighted by the magnitude of this incorrectness, thereby ...

An Age Optimized Hybrid ARQ Scheme for Polar Codes via Gaussian Approximation

IEEE Wireless Communications Letters, 2021
In this letter, we take the lead in investigating the average AoI performance for polar coded status updates over the additive white Gaussian noise (AWGN) channels.

Performance improvement of FSO communication systems using hybrid-ARQ protocols.

Applied Optics, 2021
In release 16 of the third-generation project partnership, it has been suggested that hybrid-automatic repeat request (H-ARQ) protocols can be used to ensure robust communications.

Optimum subpacket transmission for hybrid ARQ systems [PDF]

IEEE Transactions on Communications, 2006
Hybrid automatic-repeat-request (ARQ) is a flexible and efficient technique for data transmissions. In hybrid ARQ, subpacket schemes are more attractive for systems with burst errors than complete packet schemes.

Wireless scheduling with hybrid ARQ

IEEE Transactions on Wireless Communications, 2005
A model for downlink wireless scheduling is studied, which takes into account both user-channel conditions and retransmissions with packet combining hybrid [automatic repeat request (ARQ)]. Quality-of-service (QoS) requirements for each user are represented by a cost function, which is an increasing function of queue length.

Cooperative hybrid ARQ networks

2014 22nd Signal Processing and Communications Applications Conference (SIU), 2014
In this work, the performance contribution of a relay node which cooperates to a source node during the transmission of data packets from source node to destination node is investigated. The effect of diversity gain to the performance of a network consists of correlated flat-faded Rayleigh channels.

An Adaptive Hybrid ARQ Scheme

Wireless Personal Communications, 2000
A hybrid ARQ in which the transmitter adaptively selects an FEC code according to the channel condition is presented and analyzed. The code is selected according to the past transmissions and acknowledgements by an algorithm which is a generalization of that in [1].
