Viterbi decoding on a coprocessor architecture with vector parallelism

open access: yes, 2003
A programmable coprocessor architecture combining VLIW and vector parallelism has been introduced (van Berkel, K. et al., Proc. World Wireless Congress, 2003). We present the mapping of the Viterbi decoding algorithm on this architecture.

A new decoding algorithm for hidden Markov models improves the prediction of the topology of all-beta membrane proteins

open access: yesBMC Bioinformatics, 2005
Background Structure prediction of membrane proteins is still a challenging computational problem. Hidden Markov models (HMM) have been successfully applied to the problem of predicting membrane protein topology.

Adaptive decoding of convolutional codes [PDF]

open access: yesAdvances in Radio Science, 2007
Convolutional codes, which are frequently used as error correction codes in digital transmission systems, are generally decoded using the Viterbi Decoder. On the one hand the Viterbi Decoder is an optimum maximum likelihood decoder, i.e.

An Over-the-Air Multi-User Convolutional Code for URLLC

open access: yesIEEE Open Journal of the Communications Society
URLLC applications impose stringent latency and reliability requirements, making its compliance challenging due to the inherent trade-off between them. These applications typically involve the exchange of small information blocks. Convolutional codes (CC)

Multiple Chains Markov Switching Vector Autoregression

open access: yesJournal of Time Series Analysis, EarlyView.
ABSTRACT Both the U.S. stock and bond returns exhibit distinct Markovian regimes. However, because these regimes display limited coherence, conventional models typically require highly parameterized systems to adequately capture their joint distribution.

An Efficient Viterbi Decoder [PDF]

open access: yesInternational Journal of Computer Science, Engineering and Applications, 2012
Convolutional encoding with Viterbi decoding is a good forward error correction technique suitable for channels affected by noise degradation. Fangled Viterbi decoders are variants of Viterbi decoder (VD) which decodes quicker and takes less memory with no error detection capability.
