Parallel Concatenated Block Codes Constructed by Convolutional Interleavers [PDF]
IEEE Access, 2021 This paper presents the application of convolutional interleavers for constructing high performance parallel concatenated block (PCB) codes. The utilized interleaver is operated as a block interleaver, when the number of stuff bits is applied at the ...

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 ...

An Improved Blind Recognition Method of the Convolutional Interleaver Parameters in a Noisy Channel
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,

Joint Reconstruction of Reed-Solomon Encoder and Convolutional Interleaver in a Noisy Environment [PDF]
2018 International Symposium on Information Theory and Its Applications (ISITA), 2018 Blind estimation of code and interleaver parameters plays a vital role in various applications such as non-cooperative systems, adaptive modulation and coding, signal intelligence, etc. The present paper proposes novel algorithms to jointly estimate code and interleaver parameters from Reed-Solomon (RS) coded and convolutionally interleaved data stream

On interleaved, differentially encoded convolutional codes [PDF]
IEEE Transactions on Information Theory, 1999 Summary: We study a serially interleaved concatenated code construction, where the outer code is a standard convolutional code, and the inner code is a recursive convolutional code of rate 1. We focus on the ubiquitous inner differential encoder (used, in particular, to resolve phase ambiguities), double differential encoder (used to resolve both phase

Interleaved Convolutional Code and Its Viterbi Decoder Architecture [PDF]
EURASIP Journal on Advances in Signal Processing, 2003 Summary: We propose an area-efficient high-speed interleaved Viterbi decoder architecture, which is based on the state-parallel architecture with register exchange path memory structure, for the interleaved convolutional code. The state-parallel architecture uses as many add-compare-select (ACS) units as the number of trellis states.

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 ...
