Turbo Decision Aided Receivers for Clipping Noise Mitigation in Coded OFDM
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

Adaptive decoding of convolutional codes [PDF]
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 Efficient Viterbi Decoder [PDF]
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.

Interleaved Convolutional Code and Its Viterbi Decoder Architecture
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 reconfigurable Viterbi decoder architecture [PDF]
We present the design and implementation of a novel reconfigurable Viterbi decoder which provides dynamic adaptation to different constraint length and code rate convolutional codes. A decoder that supports constraint lengths from 3-7, and code rates 1/2-1/3 has been synthesized on an FPGA. With a throughput of 20 Mbps, the proposed decoder is suitable

ABSTRACT Alnus glutinosa is one of only three lineages within the order Fagales capable of establishing root nodule symbiosis (RNS). Although a fragmented genome assembly of A. glutinosa was previously available, its limited quality, combined with the lack of comprehensive transcriptomic resources, has constrained in‐depth comparative and functional ...

A parallel Viterbi decoding algorithm
AbstractIn this paper we express the Viterbi algorithm as a matrix–vector reduction in which multiplication is replaced by addition and addition by minimization. The resulting algorithm is then readily parallelized in a form suitable for implementation on a systolic processor array.

Detecting disease progression from animal movement using hidden Markov models
We demonstrate how (H)HMMs can be tailored to different epidemiological scenarios and provide a template workflow for developing and selecting Hidden Markov models to infer disease status from animal movement data. Identifying infection before mortality occurs offers a valuable early‐warning tool for population managers, reduces reliance on difficult ...
