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 ...

A New Class of Braided Block Codes Constructed by Convolutional Interleavers
MathematicsParallel Concatenated Block (PCB) codes are conventionally represented as high-rate codes with low error correcting capability. To form a reliable and outstanding code, this paper presents a modification on the structure of PCB codes, which is ...

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

Improving the performance of BICM-ID and MLC systems with different FEC codes [PDF]
Advances in Radio Science, 2013 In bandwidth limited communication systems, the high data rate transmission with performance close to capacity limits is achieved by applying multilevel modulation schemes in association with powerful forward error correction (FEC) coding, i.e.

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

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.

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,
