Single-Anchor Positioning: Multipath Processing With Non-Coherent Directional Measurements

open access: yesIEEE Access, 2020
High-accuracy indoor radio positioning can be achieved by using (ultra) wideband (UWB) radio signals. Multiple fixed anchor nodes are needed to compute the position or alternatively, specular multipath components (SMCs) extracted from radio signals can ...

iCUS: Intelligent CU Size Selection for HEVC Inter Prediction

open access: yesIEEE Access, 2020
The hierarchical quadtree partitioning of Coding Tree Units (CTU) is one of the striking features in HEVC that contributes towards its superior coding performance over its predecessors.

Representations of language in a model of visually grounded speech signal [PDF]

open access: yesAnnual Meeting of the Association for Computational Linguistics, 2017
We present a visually grounded model of speech perception which projects spoken utterances and images to a joint semantic space. We use a multi-layer recurrent highway network to model the temporal nature of spoken speech, and show that it learns to ...

On Preprocessing Of Speech Signals [PDF]

open access: yes, 2008
Preprocessing of speech signals is considered a crucial step in the development of a robust and efficient speech or speaker recognition system. In this paper, we present some popular statistical outlier-detection based strategies to segregate the silence/unvoiced part of the speech signal from the voiced portion.

Wideband TDoA Positioning Exploiting RSS-Based Clustering

open access: yesSensors, 2023
The accuracy of radio-based positioning is heavily influenced by a dense multipath (DM) channel, leading to poor position accuracy. The DM affects both time of flight (ToF) measurements extracted from wideband (WB) signals—specifically, if the bandwidth ...

A Full Loading-Based MVDR Beamforming Method by Backward Correction of the Steering Vector and Reconstruction of the Covariance Matrix

open access: yesApplied Sciences, 2022
In order to improve the performance of the diagonal loading-based minimum variance distortionless response (MVDR) beamformer, a full loading-based MVDR beamforming method is proposed in this paper. Different from the conventional diagonal loading methods,
