List Viterbi Decoding of PAC Codes [PDF]

open access: yesIEEE Transactions on Vehicular Technology, 2020
<div>Polarization-adjusted convolutional (PAC) codes are special concatenated codes in which we employ a one-to-one convolutional transform as a pre-coding step before the polar transform. In this scheme, the polar transform (as a mapper) and the successive cancellation process (as a demapper) present a synthetic vector channel to the ...

An approach for medical event detection in Chinese clinical notes of electronic health records

open access: yesBMC Medical Informatics and Decision Making, 2019
Background Medical event detection in narrative clinical notes of electronic health records (EHRs) is a task designed for reading text and extracting information. Most of the previous work of medical event detection treats the task as extracting concepts

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.

Turbo Decision Aided Receivers for Clipping Noise Mitigation in Coded OFDM

open access: yesEURASIP Journal on Wireless Communications and Networking, 2008
Orthogonal frequency division multiplexing (OFDM) is the modulation technique used in most of the high-rate communication standards. However, OFDM signals exhibit high peak average to power ratio (PAPR) that makes them particularly sensitive to

Interleaved Convolutional Code and Its Viterbi Decoder Architecture

open access: yesEURASIP 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

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.
