Application of convolutional interleavers in turbo codes with unequal error protection
Journal of Telecommunications and Information Technology, 2006 This paper deals with an application of convolu- tional interleavers in unequal error protection (UEP) turbo codes. The constructed convolutional interleavers act as block interleavers by inserting a number of stuff bits into the interleaver memories at

An Improved Blind Recognition Method of the Convolutional Interleaver Parameters in a Noisy Channel [PDF]
IEEE Access, 2019 In a digital communication system, forward error correction (FEC) codes and interleavers are implemented to code the data so as to improve the error performance, which is hindered by random and burst errors. In the context of noncooperative communication,

Blind identification of an unknown interleaved convolutional code [PDF]
2015 IEEE International Symposium on Information Theory (ISIT), 2015 We give here an efficient method to reconstruct the block interleaver and recover the convolutional code when several noisy interleaved codewords are given. We reconstruct the block interleaver without assumption on its structure.

Weight distribution of turbo codes with convolutional interleavers
IET Communications, 2007 A simple algorithm for the weight calculation of turbo codes with convolutional interleavers is presented. For codes with short interleaver lengths, the weight distributions are computed using conventionally proposed methods and then utilised together with the interleaver properties to determine the weight specifications for the code with a longer ...

Lengths for Which Fourth Degree PP Interleavers Lead to Weaker Performances Compared to Quadratic and Cubic PP Interleavers [PDF]
Entropy, 2020 In this paper, we obtain upper bounds on the minimum distance for turbo codes using fourth degree permutation polynomial (4-PP) interleavers of a specific interleaver length and classical turbo codes of nominal 1/3 coding rate, with two recursive ...
