This paper presents two simple and effective criteria for stopping the iteration process in turbo decoding with a negligible degradation of the error performance based on the cross-entropy (CE) concept.Abstract:
This paper presents two simple and effective criteria for stopping the iteration process in turbo decoding with a negligible degradation of the error performance. Both criteria are devised based on the cross-entropy (CE) concept. They are as efficient as the CE criterion, but require much less and simpler computations.read more

The art of error correcting coding
TL;DR: This chapter discusses encoding and decoding of binary BCH codes as well as some of the techniques used in the Viterbi algorithm, which simplifies the decoding process and increases the chances of success in the face of uncertainty.

A simple stopping criterion for turbo decoding
Y. Wu,Brian D. Woerner,W.J. Ebel +2 more
TL;DR: Simulations comparing the new technique with other well known stopping criteria show that the proposed SDR scheme achieves similar performance in terms of the bit error rate, frame error rate (FER), and the average number of iterations, while requiring lower complexity.

Coded modulation using superimposed binary codes
TL;DR: This correspondence investigates in a comprehensive fashion a one-layer coding/shaping scheme resembling a perfectly cooperated multiple-access system and proposes an optimal soft-input-soft-output (SISO) demapping algorithm with quadratic rather than exponential complexity.

Near optimum error correcting coding and decoding: turbo-codes
Claude Berrou,A. Glavieux +1 more
TL;DR: A new family of convolutional codes, nicknamed turbo-codes, built from a particular concatenation of two recursive systematic codes, linked together by nonuniform interleaving appears to be close to the theoretical limit predicted by Shannon.

Iterative decoding of binary block and convolutional codes
TL;DR: Using log-likelihood algebra, it is shown that any decoder can be used which accepts soft inputs-including a priori values-and delivers soft outputs that can be split into three terms: the soft channel and aPriori inputs, and the extrinsic value.
