Iterative estimation method for random interleaver of Turbo codes

open access: yesTongxin xuebao, 2015
Channel coding parameter analysis meant reversely analyzing and estimating the coding parameters,and was one of the key techniques for intelligent communication,information interception and so on.Since Turbo codes were widely used in communication ...

On Rate-Compatible Punctured Turbo Codes Design

open access: yesEURASIP Journal on Advances in Signal Processing, 2005
We propose and compare some design criteria for the search of good systematic rate-compatible punctured turbo code (RCPTC) families. The considerations presented by S. Benedetto et al.

Interleaving Gains for Receive Diversity Schemes of Distributed Turbo Codes in Wireless Half–Duplex Relay Channels [PDF]

open access: yesRadioengineering, 2015
This paper proposes the interleaving gain in two different distributed turbo-coding schemes: Distributed Turbo Codes (DTC) and Distributed Multiple Turbo Codes (DMTC) for half-duplex relay system as an extension of our previous work on turbo coding ...

An Efficient SF-ISF Approach for the Slepian-Wolf Source Coding Problem

open access: yesEURASIP Journal on Advances in Signal Processing, 2005
A simple but powerful scheme exploiting the binning concept for asymmetric lossless distributed source coding is proposed. The novelty in the proposed scheme is the introduction of a syndrome former (SF) in the source encoder and an inverse syndrome ...

Sensitivity analysis of the channel estimation deviation to the MAP decoding algorithm

open access: yesTongxin xuebao, 2006
As a necessary input parameter for MAP decoding algorithm,SNR was normally obtained from the channel estimation unit.Corresponding research indicated that SNR estimation deviation degraded significantly the performance of Turbo decoding.MAP decoding ...

Improving 3D-Turbo Code's BER Performance with a BICM System over Rayleigh Fading Channel [PDF]

open access: yesRadioengineering, 2016
Classical Turbo code suffers from high error floor due to its small Minimum Hamming Distance (MHD). Newly-proposed 3D-Turbo code can effectively increase the MHD and achieve a lower error floor by adding a rate-1 post encoder.

Space-Time Turbo Coded Modulation: Design and Applications

open access: yesEURASIP Journal on Advances in Signal Processing, 2002
A design method for recursive space-time trellis codes and parallel-concatenated space-time turbo coded modulation is proposed that can be applied to an arbitrary existing space-time trellis code.

On the Error Statistics of Turbo Decoding for Hybrid Concatenated Codes Design

open access: yesJournal of Communications Software and Systems, 2019
In this paper we propose a model for the generation of error patterns at the output of a turbo decoder. One of the advantages of this model is that it can be used to generate the error sequence with little effort.

A Theoretical Framework for Soft-Information-Based Synchronization in Iterative (Turbo) Receivers

open access: yesEURASIP Journal on Wireless Communications and Networking, 2005
This contribution considers turbo synchronization, that is to say, the use of soft data information to estimate parameters like carrier phase, frequency, or timing offsets of a modulated signal within an iterative data demodulator.
