Perceptual coding of digital audio
T. Painter,Andreas Spanias +1 more
TL;DR: This paper reviews methodologies that achieve perceptually transparent coding of FM- and CD-quality audio signals, including algorithms that manipulate transform components, subband signal decompositions, sinusoidal signal components, and linear prediction parameters, as well as hybrid algorithms that make use of more than one signal model.
Journal ArticleDOI
Speech coding: a tutorial review
TL;DR: The objective of this paper is to provide a tutorial overview of speech coding methodologies with emphasis on those algorithms that are part of the recent low-rate standards for cellular communications.
Proceedings Article
Attend and diagnose: Clinical time series analysis using attention models
TL;DR: In this paper, a self-attention mechanism is employed for clinical time-series modeling, which employs a masked, self attention mechanism, and uses positional encoding and dense interpolation strategies for incorporating temporal order.
Journal ArticleDOI
Smart-antenna systems for mobile communication networks. Part 1. Overview and antenna design
TL;DR: This paper focuses on the interaction and integration of several critical components of a mobile communication network using smart-antenna systems, and the observed dependence of the overall network throughput on the design of the adaptive antenna system and its underlying signal processing algorithms.
Proceedings ArticleDOI
Smart antennas for wireless communications
TL;DR: The objective is to design an adaptive antenna that directs the maximum radiation of the antenna pattern toward the signal-of-interest (SOI), and places nulls toward the signals of interest (SNOI) in the next generation 20 GHz wireless communications systems.
