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.

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.

Switching threshold and coding-rate optimisation for turbo convolutional and turbo BCH coded adaptive modulation [PDF]
The 57th IEEE Semiannual Vehicular Technology Conference, 2003. VTC 2003-Spring., 2004 Decision feedback equaliser (DFE) aided turbo coded wideband adaptive quadrature amplitude modulation (AQAM) is capable of accommodating the temporal channel quality variation of fading channels. A procedure is suggested for determining the AQAM switching thresholds and the specific turbo coding rates capable of maintaining the target BER, while aiming

Advanced Science, EarlyView.RNA structural profiling of Turnip Yellow Mosaic Virus by DMS‐MaPseq and DREEM analyses uncover that viral genome‐wide RSS is highly complicated and heterogeneous, with alternative RSSs widely distributed across the genome. Notably, the viral 3’ tRNA‐like structure adopts alternative conformations in vivo.

Combination of turbo equalisation and Turbo Trellis-coded modulation with low complexity
IET Communications, 2007 A novel low-complexity scheme of Turbo Trellis-coded modulation (TCM) iterative equalisation and decoding is presented, which serially concatenates a soft-input-soft-output equaliser and symbol-by-symbol Turbo TCM (TTCM) decoder through an iterative process in order to realise iterative equalisation and decoding process.

Biotechnology and Bioengineering, EarlyView.ABSTRACT Yeast sugar transporters have highly evolved for preferential glucose transport, a significant roadblock for utilizing non‐glucose sugars in renewable feedstocks such as lignocellulosic biomass. To enable simultaneous transport of multiple sugars, native hexose transporters were replaced by SWEET7p from Arabidopsis thaliana in engineered ...

Cardiac remodeling and arrhythmia in a mouse model of Depdc5 haploinsufficiency
Epilepsia, EarlyView.Abstract Objective Some ion channel genes linked to developmental and epileptic encephalopathy (DEE) are also linked to cardiac arrhythmia, leading to the hypothesis that predisposition to cardiac arrhythmias may contribute to the complex disease presentation of DEE and possibly to the mechanism of sudden unexpected death in epilepsy.
