Variable-Rate Transmission for Incremental Redundancy Hybrid ARQ
2010 IEEE Global Telecommunications Conference GLOBECOM 2010, 2010We analyze the throughput achievable by a truncated Hybrid ARQ protocol (HARQ) using incremental redundancy (IR) when transmitting over a block-fading channel whose state is unknown at the transmit end. We allow the transmission rates to vary, optimize them, and show that such a variable-rate HARQ-IR provides gains with respect to a fixed-rate ...

Chains of cyclic codes, Construction X and incremental redundancy
2008 IEEE Information Theory Workshop, 2008It is shown that chains of cyclic codes in conjunction with constructions X and XX can be used to efficiently construct sequences of linear codes for application in incremental redundancy communications. In addition to using a CRC for error detection, a novel CRC-less approach to error detection, which is based on the confidence level of the soft ...

Approaching capacity using incremental redundancy without feedback
2017 IEEE International Symposium on Information Theory (ISIT), 2017Variable-length codes with incremental redundancy controlled by feedback allow a system to approach capacity with short average blocklengths and thus relatively low-complexity decoders. This paper shows how to use those same variable-length codes with incremental redundancy to approach capacity without feedback.

Performance of hybrid-ARQ with incremental redundancy over relay channels [PDF]
In this paper, we consider a relay network consisting of a source, a relay, and a destination. The source transmits a message to the destination using hybrid automatic repeat request (HARQ) with incremental redundancy (IR). The relay overhears the transmitted messages over the different HARQ rounds and tries to decode the data packet.

An Incremental Learning Framework for Human-Like Redundancy Optimization of Anthropomorphic Manipulators [PDF]
Recently, the human-like behavior on anthropomorphic robot manipulators are increasingly accomplished by the kinematic model estabilshing the relationship of an anthropomorphic manipulator and human arm motions. Notably, the growth and broad availability

On Large Deviations of HARQ with Incremental Redundancy over Fading Channels
IEEE Communications Letters, 2012The hybrid automatic repeat request (HARQ) protocol with incremental redundancy (IR) or HARQ-IR protocol is an effective means to transmit signals over unreliable channels. It can achieve ergodic capacity with limited feedback of channel state information (CSI) from a receiver.

Performance and Delay Analysis of Hybrid ARQ With Incremental Redundancy Over Double Rayleigh Fading Channels [PDF]
In this paper, we study the performance of hybrid automatic repeat request (HARQ) with incremental redundancy over double Rayleigh channels, a common model for the fading amplitude of vehicle-to-vehicle communication systems.

Outage-Optimal Power Allocation for Hybrid ARQ with Incremental Redundancy [PDF]
-We consider the optimization of power in incremental redundancy (IR) based hybrid automatic repeat request (HARQ) schemes when the maximum number of (re)transmissions is fixed.

Energy Optimization for Incremental Redundancy Hybrid-ARQ
2019 53rd Asilomar Conference on Signals, Systems, and Computers, 2019We consider energy optimization for incremental redundancy (IR) hybrid automatic repeat request (HARQ) over independent block-fading channels. We optimize the code rates in different transmission rounds to minimize the overall energy consumption of HARQ, subject to an overall packet error rate constraint.
