An error bound analysis for M-DPSK in frequency-selective Rayleigh fading channel with diversity reception [PDF]

open access: yes, 1994
A theoretical upper bound is presented to calculate the error probability for raised cosine filtered M-ary differential phase-shift keying (RC M-DPSK) in frequency-selective Rayleigh fading channels.

Fast algorithms for fundamental frequency estimation in autoregressive noise [PDF]

open access: yes, 2021
Many signals can accurately be modelled as a periodic function in coloured noise. An important parameter of the periodic function is the fundamental frequency.

Fundamental limits to frequency estimation: a comprehensive microscopic perspective [PDF]

open access: yes, 2017
We consider a metrology scenario in which qubit-like probes are used to sense an external field that affects their energy splitting in a linear fashion. Following the frequency estimation approach in which one optimizes the state and sensing time of the ...

Tonal Contour Generation for Isarn Speech Synthesis Using Deep Learning and Sampling-Based F0 Representation

open access: yesApplied Sciences, 2020
The modeling of fundamental frequency (F0) in speech synthesis is a critical factor affecting the intelligibility and naturalness of synthesized speech. In this paper, we focus on improving the modeling of F0 for Isarn speech synthesis. We propose the F0

Vowel Classification Based on Fundamental Frequency and Formant Frequencies [PDF]

open access: yesJournal of Speech, Language, and Hearing Research, 1993
A quadratic discriminant classification technique was used to classify spectral measurements from vowels spoken by men, women, and children. The parameters used to train the discriminant classifier consisted of various combinations of fundamental frequency and the three lowest formant frequencies.

A Kalman-based Fundamental Frequency Estimation Algorithm [PDF]

open access: yes, 2017
Fundamental frequency estimation is an important task in speech and audio analysis. Harmonic model-based methods typically have superior estimation accuracy. However, such methods usually as- sume that the fundamental frequency and amplitudes are station-

Interpretations of Frequency Domain Analyses of Neural Entrainment: Periodicity, Fundamental Frequency, and Harmonics

open access: yesFrontiers in Human Neuroscience, 2016
Brain activity can follow the rhythms of dynamic sensory stimuli, such as speech and music, a phenomenon called neural entrainment. It has been hypothesized that low-frequency neural entrainment in the neural delta and theta bands provides a potential ...

Carcinomas and Carcinoid Tumors of the Lungs and Bronchi in Children and Adolescents: The EXPeRT Recommendations

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Primary lung carcinomas and bronchial carcinoid tumors (BC) are very rare malignancies in childhood. While typical BC and mucoepidermoid carcinomas are mostly low‐grade, localized tumors with a more favorable prognosis than in adults, necessitating avoidance of overtreatment, adenocarcinomas of the lung are often diagnosed at advanced disease ...

An Arduino-Based Resonant Cradle Design with Infant Cries Recognition

open access: yesSensors, 2015
This paper proposes a resonant electric cradle design with infant cries recognition, employing an Arduino UNO as the core processor. For most commercially available electric cradles, the drive motor is closely combined with the bearing on the top ...
