Review and Analysis of Digital Signal Processing Algorithms for Coherent Optical Satellite Links
International Journal of Satellite Communications and Networking, Volume 43, Issue 3, Page 229-250, May/June 2025.ABSTRACT Coherent optical satellite links enable high‐throughput communication and high accuracy ranging to and between satellites. Due to the ever‐increasing demand for throughput, wavelength division multiplexing of polarization multiplexed optical signals is being considered as a solution to provide high‐speed optical satellite links.

Improved order selection method for hidden Markov models: A case study with movement data
Methods in Ecology and Evolution, Volume 16, Issue 6, Page 1215-1227, June 2025.Abstract Hidden Markov models (HMMs) are a versatile statistical framework commonly used in ecology to characterize behavioural patterns from animal movement data. In HMMs, the observed data depend on a finite number of underlying hidden states, generally interpreted as the animal's unobserved behaviour. The number of states is a crucial hyperparameter,

Throughput improvement on bidirectional Fano algorithm [PDF]
, 2010 Recently, we introduced a bidirectional Fano algorithm (BFA) [10] which can achieve much higher decoding throughput compared to the regular unidirectional Fano algorithm (UFA), especially at low signal-to-noise-ratio (SNR).

Separating Noisy TCP/IP Session Flows Based on Natural Redundancy Decoding
IET Communications, Volume 19, Issue 1, January/December 2025.This paper optimizes the mean shift clustering algorithm for session flow separation in noisy environments by introducing a channel matching index for better window radius selection and using a majority decision mechanism for clustering centre updates. Tested on the CIC‐IDS‐2017 dataset, the proposed method achieves flow separation at a bit error rate ...

On Viterbi decoding for time-varying convolutional codes
, 1978 The Viterbi decoding technique has been extended for time-varying convolutional codes. The problem has been presented as a discrete-times, time-varying regulator control problem, and dynamic programming has been utilized to explain the decoding ...

A Novel Method for Decoding Any High-Order Hidden Markov Model
Discrete Dynamics in Nature and Society, 2014 This paper proposes a novel method for decoding any high-order hidden Markov model. First, the high-order hidden Markov model is transformed into an equivalent first-order hidden Markov model by Hadar’s transformation. Next, the optimal state sequence of
