Scandinavian Journal of Statistics, EarlyView.ABSTRACT Two major tasks in applications of hidden Markov models are to (i) compute distributions of summary statistics of the hidden state sequence, and (ii) decode the hidden state sequence. We describe finite Markov chain imbedding (FMCI) and hybrid decoding to solve each of these two tasks.

A parallel Viterbi decoder for block cyclic and convolution codes
, 2005 We present a parallel version of Viterbi's decoding procedure, for which we are able to demonstrate that the resultant task graph has restricted complexity in that the number of communications to or from any processor cannot exceed 4 for BCH codes.

Linking the Movement Behavior of the Laptev Sea Walrus to Sea Ice and Resource Dynamics
Marine Mammal Science, Volume 42, Issue 4, October 2026.ABSTRACT The walrus subspecies inhabiting the Laptev Sea (Odobenus rosmarus divergens) remains one of the least studied walrus taxa and occurs in a region undergoing rapid environmental change driven by climate warming and increasing human activity. We conducted the first satellite telemetry study of walruses in this region, tracking 14 individuals ...

Graph-Based Codes and Iterative Decoding [PDF]
, 2003 The field of error correcting codes was revolutionized by the introduction of turbo codes in 1993. These codes demonstrated dramatic performance improvements over any previously known codes, with significantly lower complexity.

Interleaved Convolutional Code and Its Viterbi Decoder Architecture
EURASIP Journal on Advances in Signal Processing, 2003 We propose an area-efficient high-speed interleaved Viterbi decoder architecture, which is based on the state-parallel architecture with register exchange path memory structure, for interleaved convolutional code. The state-parallel architecture uses as

A New List Decoding Algorithm for Short-Length TBCCs With CRC
IEEE Access, 2018 In this paper, a new list decoding algorithm for tail-biting convolutional codes (TBCCs) with a cyclic redundancy check (CRC) is proposed, where the CRC is considered as a concatenated outer code.

Hidden Markov graphical models with state‐dependent generalized hyperbolic distributions
Canadian Journal of Statistics, Volume 54, Issue 3, September 2026.Abstract In this article, we develop a novel hidden Markov graphical model to investigate time‐varying interconnectedness between different financial markets. To identify conditional correlation structures under varying market conditions and accommodate shape features embedded in financial time series, we rely upon the generalized hyperbolic family of ...

CNS Neuroscience &Therapeutics, Volume 32, Issue 9, September 2026.Using hidden Markov models (HMM) to analyze dynamic brain states from resting‐state fMRI, this study identifies opposing temporal dynamics in Parkinson's disease (PD) and progressive supranuclear palsy (PSP). PD patients show reduced fractional occupancy in unimodal networks, while PSP patients exhibit increased occupancy and prolonged duration in ...
