Nested turbo codes for the costa problem [PDF]

open access: yes, 2008
Driven by applications in data-hiding, MIMO broadcast channel coding, precoding for interference cancellation, and transmitter cooperation in wireless networks, Costa coding has lately become a very active research area.

Iterative channel estimation and decoding algorithm for quasi-coherent demodulation of Turbo coded GMSK signals

open access: yesTongxin xuebao, 2006
A new simple iterative channel estimation algorithm for quasi-coherent demodulation Turbo coded GMSK signals was presented. Based on the iterative decoding principle of Turbo code, the algorithm improved the channel esti- mation accuracy using output of ...

Low-Complexity Multiple-Component Turbo Decoding Aided Hybrid ARQ

open access: yes, 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

Source-Difference-Based Mapping Improves Spatial Modulation

open access: yesIEEE Open Journal of Vehicular Technology, 2023
A new multi-antenna transmission scheme, referred to as difference-based spatial modulation (DBSM), is proposed to enhance the reliability of spatial modulation (SM).

Look-up Table Based Deferred-Iteration Aided Low-Complexity Turbo Hybrid ARQ

open access: yes, 2011
Since the introduction of turbo code aided Hybrid Automatic Repeat reQuest (HARQ) schemes, their complexity reduction has drawn research attention. In our previous work, we proposed an Early Stopping (ES) strategy for a turbo HARQ scheme, which results ...

Analysis of iteration control for turbo decoders in turbo synchronization applications [PDF]

open access: yesAdvances in Radio Science, 2009
Wireless data transmission results in frequency and phase offsets of the signal in the receiver. In addition, the received symbols are corrupted by noise.

Genetic dissection of human ABCE1 in yeast reveals separable requirements for ribosome recycling and suppression of aberrant reinitiation

open access: yesFEBS Open Bio, EarlyView.
Human ABCE1 cannot functionally replace its yeast ortholog. Yeast–human chimera analysis identified NBD1 as a major interspecies barrier. Genetic screening yielded hABCE1 revertants that rescue yeast viability but fail to suppress aberrant translation reinitiation in the 3′ UTR.

Forward and backward RLS-DDCE processing in MIMO-OFDM spatial multiplexing receivers [PDF]

open access: yesAdvances in Radio Science, 2010
In this paper we present a novel approach in frequency domain channel estimation technique. Our proposal is based on the recursive least squares (RLS) algorithm combined with the decision making process called decision directed channel estimation (RLS ...

Is an Apple an Orange? A Large Language Model Benchmark for Candidate Term Extraction and Subclass Decisions Against Upper Ontologies in Engineering and Materials Science

open access: yesAdvanced Engineering Materials, EarlyView.
Building machine‐readable vocabularies for materials science is slow, expert‐driven work. This study benchmarks 13 large language models on two of its first steps: finding candidate terms in engineering articles and deciding where they belong in a class hierarchy.
