Deferred-Iteration Aided Low-Complexity Turbo Hybrid ARQ Relying on a Look-up Table [PDF]

open access: yes, 2011
Since the introduction of turbo code aided Hybrid Automatic Repeat reQuest (HARQ) schemes, their complexity reduction has drawn research attention. In our previous work, we proposed an Early Stopping (ES) strategy for a turbo HARQ scheme, which results ...

Recurrent neural network based turbo decoding algorithms for different code rates

open access: yesJournal of King Saud University: Computer and Information Sciences, 2022
Application of deep learning to error control coding is gaining special attention and neural network architectures on decoding are approached to compare with conventional ones. Turbo codes conventionally use BCJR algorithm for decoding.

Turbo codes and turbo algorithms

open access: yesJournal of Communications Software and Systems, 2017
In the first part of this paper, several basic ideas that prompted the coming of turbo codes are commented on. We then present some personal points of view on the main advances obtained in past years on turbo coding and decoding such as the circular trellis termination of recursive systematic convolutional codes and double-binary turbo codes associated

Influence of Vane Structure on Flow Field in Turbo-air Classifier

open access: yesShiyou jixie, 2021
Turbo-air classifiers have low classifying precision and efficiency, which are mainly resulted from its internal structure. In this study, based on the air flow trajectory equation, three structural types of guide vanes are designed including straight ...

Frequency-Domain Turbo Equalisation in Coded SC-FDMA Systems: EXIT Chart Analysis and Performance [PDF]

open access: yes, 2012
In this paper, we investigate the achievable performance of channel coded single-carrier frequency division multiple-access (SC-FDMA) systems employing various detection schemes, when communicating over frequency-selective fading channels.

Numerical Investigation: Effect of Stator Vanes on Turbocharger Turbine Performance

open access: yesInternational Journal of Rotating Machinery, 2014
With reduced turbo lag and better transient response, the introduction of VTG stator guide vanes improved turbocharger performance at all the engine operating conditions. The VTG system accelerates and maneuvers exhaust gas flow to the turbine. Favorable
