Online Modeling and Prediction of the Large-Scale Temporal Variation in Underwater Acoustic Communication Channels

IEEE Access, 2018
Influenced by environmental conditions, underwater acoustic communication channels exhibit dynamics on various time scales. The channel dynamics within a short transmission duration have been extensively studied in existing research.

Safe-RTSKF: A Safety-Constrained Recursive Two-Stage Kalman Filter for Robust Sensor State Estimation in Strongly Nonlinear Systems

Sensors
Robust state estimation is essential for sensor systems operating under strong nonlinearity, high uncertainty, and outlier-contaminated measurements. Recursive two-stage Kalman filtering provides an interpretable framework for systems with multiplicative

Modeling of Currency Covolatilities [PDF]

Statistika: Statistics and Economy Journal, 2019
The paper deals with dynamic modeling of currency portfolios. In contrast to univariate models of exchange rates and their returns one applies multivariate time series models of the type GARCH that are capable of capturing not only conditional ...

HiGoReg: A Hierarchical Grouping Strategy for Point Cloud Registration

Remote Sensing
To address the persistent computational bottlenecks in point cloud registration, this paper proposes a hierarchical grouping strategy named HiGoReg. This method incrementally updates the pose of the source point cloud via a hierarchical mechanism, while ...

Localizing weather forecasts for enhanced heat load forecast accuracy in urban district heating systems

International Journal of Sustainable Energy
Weather forecasts are essential for district heating (DH) utility operations as they prepare the utility for future consumption, thus ensuring optimal operation by supplying sufficient heat while keeping costs low. Weather forecasts are usually converted

Self-Tuning Blind Identification and Equalization of IIR Channels

EURASIP Journal on Advances in Signal Processing, 2003
This paper considers self-tuning blind identification and equalization of fractionally spaced IIR channels. One recursive estimator is used to generate parameter estimates of the numerators of IIR systems, while the other estimates denominator of IIR ...
