Nonbinary LDPC-Coded Modulation System in High-Speed Mobile Communications
IEEE Access, 2018 As a class of capacity-approaching codes, nonbinary low-density parity-check (LDPC) codes have attracted much attention because of noticeable performance.

Distributed Turbo Trellis Coded Modulation for Cooperative Communications [PDF]
2009 IEEE International Conference on Communications, 2009 In this contribution, we propose a Distributed Turbo Trellis Coded Modulation (DTTCM) scheme for cooperative communications. The DTTCM scheme is designed based on its decoding convergence with the aid of non-binary Extrinsic Information Transfer (EXIT) charts. The source node transmits TTCM symbols to both the relay and the destination nodes during the

Improving 3D-Turbo Code's BER Performance with a BICM System over Rayleigh Fading Channel [PDF]
Radioengineering, 2016 Classical Turbo code suffers from high error floor due to its small Minimum Hamming Distance (MHD). Newly-proposed 3D-Turbo code can effectively increase the MHD and achieve a lower error floor by adding a rate-1 post encoder.

Advanced Science, EarlyView.Liberation of ferulic acid by gut microbial feruloyl esterase mediates cognitive enhancement of germinated quinoa (GQF) on obese mice. Ferulic acid enriched in GQF is released by gut microbes Roseburia hominis and R. intestinalis and subsequently mediates the neuroprotective effects of GQF on obesity‐induced cognitive decline by activating hippocampal ...

Performance of Antenna Diversity with Turbo Trellis Coded Modulation Over Nakagami Channels
Electrica, 2019 In this paper, we will use the Space Time Block codes for antenna diversity, and the performance of Space-Time – Turbo Trellis Coded Modulation (ST-TTCM) is investigated over Nakagami channels.

Codebook Design for PD-SCMA NOMA Systems
IEEE Access, 2023 The hybrid power domain sparse code non-orthogonal multiple access (PD-SCMA) scheme multiplexes multiple users on a single resource element (RE) both in power and code domains, thus achieving a superior spectral efficiency.

PERFORMANCE EVALUATION OF TURBO CODED OFDM SYSTEMS AND APPLICATION OF TURBO DECODING FOR IMPULSIVE CHANNEL [PDF]
ICTACT Journal on Communication Technology, 2010 A comparison of the performance of hard and soft-decision turbo coded Orthogonal Frequency Division Multiplexing systems with Quadrature Phase Shift Keying (QPSK) and 16-Quadrature Amplitude Modulation (16-QAM) is considered in the first section of this ...

Animal Research and One Health, EarlyView.vvrr1, a small RNA, post‐transcriptionally represses the transcriptional regulator LeuO, which directly inhibits the VarS/VarA two‐component system. This triggers a Csr cascade that relieves LuxO repression, ultimately modulating exopolysaccharide production to control biofilm formation and virulence in Vibrio alginolyticus.
