Performance evaluation of parallel concatenated codes [PDF]
, 1995 A parallel concatenated coding scheme consists of two simple systematic constituent encoders linked by an interleaver. The input bits to the first encoder are scrambled by the interleaver before entering the second encoder.

Personalized Network‐Guided Neuromodulation Enhances Human Working Memory
Advanced Science, EarlyView.A personalized neuromodulation framework combining individualized functional brain network targeting with real‐time neural decoding is introduced. Using concurrent TMS–fMRI, participant‐specific stimulation targets and optimal frequencies are identified. Only optimal‐frequency stimulation improves working memory across sessions.

Design and Evaluation of Adaptive (Serial/Parallel) Concatenated Convolutional Codes
Journal of Engineering and Sustainable Development, 2006 In this paper, parallel Concatenated Convolutional Codes (PCCCs) is modeled as a special case of Serial Concatenated Convolutional Code (SCCCs). Consequently, resulting in Adaptive (parallel/serial) concatenated convolutional code in which the same ...

Ultra‐Wide‐Field Noninvasive Imaging Through Scattering Media Via Physics‐Guided Deep Learning
Advanced Science, EarlyView.We propose a physics‐guided adaptive dual‐domain learning method for ultra‐wide‐field noninvasive imaging through scattering media, namely UNI‐Net. Our method not only reduces the requirement for real experimental data by an order of magnitude but also enables clear imaging of complex scenes with an ultra‐large field of view, which is 164 times the OME

On the Error Statistics of Turbo Decoding for Hybrid Concatenated Codes Design
Journal of Communications Software and Systems, 2019 In this paper we propose a model for the generation of error patterns at the output of a turbo decoder. One of the advantages of this model is that it can be used to generate the error sequence with little effort.

Comparative Study of Turbo Equalization Schemes using Convolutional, Convolutional Turbo, and Block-Turbo Codes [PDF]
, 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 $R \le 1/2$.

Low-Complexity Multiple-Component Turbo Decoding Aided Hybrid ARQ [PDF]
, 2011 Previous research has focused on improving the throughput of Hybrid Automatic Repeat reQuest (HARQ) schemes. However, since turbo codes have been introduced into HARQ schemes, their complexity has increased owing to the iterative Bahl, Cocke, Jelinek and

Efficient Computation of EXIT Functions for Nonbinary Iterative Decoding [PDF]
, 2006 The calculation of nonbinary extrinsic information transfer charts for the iterative decoding of concatenated index-based codes is addressed. We show that the extrinsic information at the output of a constituent a posteriori probability decoder can be ...

Quasi-cyclic Generalized LDPC codes with low error floors [PDF]
, 2008 In this paper, a novel methodology for designing structured generalized LDPC (G-LDPC) codes is presented. The proposed design results in quasi-cyclic G-LDPC codes for which efficient encoding is feasible through shift-register-based circuits.
