State Space Parallelization Method for a 16-Bit Turbo Encoder [PDF]

open access: yesEngineering and Technology Journal, 2019
Turbo codes are widely used in digital communication systems. Their ability to reach the Shannon channel capacity made it the choice for most of the communication systems.

Irregular turbo code design for the binary erasure channel [PDF]

open access: yesarXiv, 2008
In this paper, the design of irregular turbo codes for the binary erasure channel is investigated. An analytic expression of the erasure probability of punctured recursive systematic convolutional codes is derived. This exact expression will be used to track the density evolution of turbo codes over the erasure channel, that will allow for the design ...

The Error-Pattern-Correcting Turbo Equalizer

open access: yes, 2010
The error-pattern correcting code (EPCC) is incorporated in the design of a turbo equalizer (TE) with aim to correct dominant error events of the inter-symbol interference (ISI) channel at the output of its matching Viterbi detector. By targeting the low

Threshold Based Iteration Stopping Criterion for Turbo Codes and for Scheme Combining a Turbo Code and a Golden Space-Time Block Code

open access: yesAdvances in Electrical and Computer Engineering, 2014
This paper proposes an iteration stopping criterion for turbo decoding with Benedetto's decoding algorithm based on a posteriori probabilities. This stopping criterion is used in two schemes.

Methods for the Reconstruction of Parallel Turbo Codes [PDF]

open access: yesarXiv, 2010
We present two new algorithms for the reconstruction of turbo codes from a noisy intercepted bitstream. With these algorithms, we were able to reconstruct various turbo codes with realistic parameter sizes. To the best of our knowledge, these are the first algorithms able to recover the whole permutation of a turbo code in the presence of high noise ...

Serial vs. Parallel Turbo-Autoencoders and Accelerated Training for Learned Channel Codes [PDF]

open access: yesarXiv, 2021
Attracted by its scalability towards practical codeword lengths, we revisit the idea of Turbo-autoencoders for end-to-end learning of PHY-Layer communications. For this, we study the existing concepts of Turbo-autoencoders from the literature and compare the concept with state-of-the-art classical coding schemes.

Turbo Decoding on the Binary Erasure Channel: Finite-Length Analysis and Turbo Stopping Sets [PDF]

open access: yesIEEE Trans. Inf. Theory, vol. 53, no. 11, pp. 4059-4075, Nov. 2007, 2006
This paper is devoted to the finite-length analysis of turbo decoding over the binary erasure channel (BEC). The performance of iterative belief-propagation (BP) decoding of low-density parity-check (LDPC) codes over the BEC can be characterized in terms of stopping sets.

Turbo codes: the phase transition [PDF]

open access: yesThe European Physical Journal B, 2000
Turbo codes are a very efficient method for communicating reliably through a noisy channel. There is no theoretical understanding of their effectiveness. In [1] they are mapped onto a class of disordered spin models. The analytical calculations concerning these models are reported here.
