An improved iterative decoding algorithm for block turbo codes
2006 IEEE International Symposium on Information Theory, 2006 Since the introduction of the block turbo code (BTC) except, several soft-input/soft-output (SISO) algorithms have been used in order to softly decode product codes.

Comparative study of turbo equalization schemes using convolutional, convolutional turbo, and block-turbo codes [PDF]
IEEE Transactions on Wireless Communications, 2002 Turbo equalizers have been shown to be successful in mitigating the effects of inter-symbol interference introduced by partial response modems and by dispersive channels for code rates of R/spl les/ 1/2.

Inter-Block Permuted Turbo Codes [PDF]
arXiv, 2006 The structure and size of the interleaver used in a turbo code critically affect the distance spectrum and the covariance property of a component decoder's information input and soft output. This paper introduces a new class of interleavers, the inter-block permutation (IBP) interleavers, that can be build on any existing "good" block-wise interleaver ...

Design and Implementation of Shared Memory for Turbo and LDPC Code Interleaver
Wireless Communications and Mobile Computing, 2022 In 4G turbo and 5G LDPC, in order to realize a flexible, low-power, low-cost shared general-purpose block interleaving hardware module, it faces the challenges of interleaving structure integration, fewer gate circuits, parallel multistream operation ...

Massively parallel computation of globally optimal shortest paths with curvature penalization
Concurrency and Computation: Practice and Experience, Volume 35, Issue 2, 25 January 2023., 2023 Abstract We address the computation of paths globally minimizing an energy involving their curvature, with given endpoints and tangents at these endpoints, according to models known as the Reeds‐Shepp car (reversible and forward variants), the Euler‐Mumford elasticae, and the Dubins car. For that purpose, we numerically solve degenerate variants of the

Destabilization of mutated human PUS3 protein causes intellectual disability
Human Mutation, Volume 43, Issue 12, Page 2063-2078, December 2022., 2022 The homodimer of pseudouridine synthase 3 converts uridines at position 39 in tRNAs to pseudouridine (ψ), which affects tRNA stability and regulates RNA–protein interactions. Several patient‐derived variants of PUS3 have been associated with neurodegenerative diseases.

On The Performance of Turbo Codes With Convolutional Interleavers [PDF]
, 2005 In this paper, some issues governing the block-wise performance of convolutional interleavers used in turbo codes are presented. Two different constructions of convolutional interleaver differing by the position of stuff bits in the interleaved data ...

Coding theorems for turbo code ensembles [PDF]
, 2002 This paper is devoted to a Shannon-theoretic study of turbo codes. We prove that ensembles of parallel and serial turbo codes are "good" in the following sense.
