E-model MOS Estimate Improvement through Jitter Buffer Packet Loss Modelling

open access: yesAdvances in Electrical and Electronic Engineering, 2011
Proposed article analyses dependence of MOS as a voice call quality (QoS) measure estimated through ITU-T E-model under real network conditions with jitter. In this paper, a method of jitter effect is proposed.

Practical Limits on Nanosatellite Telescope Pointing: The Impact of Disturbances and Photon Noise

open access: yesFrontiers in Astronomy and Space Sciences, 2021
Accurate and stable spacecraft pointing is a requirement of many astronomical observations. Pointing particularly challenges nanosatellites because of an unfavorable surface area–to-mass ratio and a proportionally large volume required for even the ...

Traffic Shaping With Optical-Wireless Cooperative Control to Reduce Uplink Jitter Due to Radio Transmission

open access: yesIEEE Access, 2023
Beyond 5th generation (5G) and 6th generation (6G) mobile systems require not only low latency but also low jitter for deterministic services such as remote operation.

Analysis and equalization of data-dependent jitter [PDF]

open access: yes, 2006
Data-dependent jitter limits the bit-error rate (BER) performance of broadband communication systems and aggravates synchronization in phase- and delay-locked loops used for data recovery.

Improving temporal resolution of ultrafast electron diffraction by eliminating arrival time jitter induced by radiofrequency bunch compression cavities [PDF]

open access: yes, 2017
The temporal resolution of sub-relativistic ultrafast electron diffraction (UED) is generally limited by radio frequency (RF) phase and amplitude jitter of the RF lenses that are used to compress the electron pulses.

Development of a tool to objectively identify normal human voice

open access: yesBLDE University Journal of Health Sciences, 2020
Acoustic analysis is used to assist differential diagnosis, documentation and evaluation of treatment for voice disorders. Clinical data has shown that Jitter, Shimmer, Mean Pitch and Harmonic Noise Ratio are the indices of voice pathology.

On the jitter of mode-locked pulses introduced by an optical fibre [PDF]

open access: yes, 1993
Measurements on the jitter of mode-locked pulses of a Nd:YLF laser after travelling through an optical fibre are presented. For low powers self phase modulation occurs which leaves the jitter unaltered.

An Enhanced Technique for Ultrasonic Flow Metering Featuring Very Low Jitter and Offset

open access: yesSensors, 2016
This paper proposes a new, improved method for water flow metering. It applies to a transit time ultrasonic flow meter device. In principle, the flow of a given liquid in a pipe is obtained by measuring the transit times of an ultrasonic wave in the ...

Low-Jitter Clock Multiplication: a Comparioson between PLLs and DLLs [PDF]

open access: yes, 2002
This paper shows that, for a given power budget, a practical phase-locked loop (PLL)-based clock multiplier generates less jitter than a delay-locked loop (DLL) equivalent. This is due to the fact that the delay cells in a PLL ring-oscillator can consume

Minimum jitter-based adaptive decision feedback equaliser for giga-bit-per-second serial links

open access: yesThe Journal of Engineering, 2015
This study presents a minimum jitter-based adaptive decision feedback equaliser (DFE) for giga-bit-per-second (Gbps) serial links. The adaptation in search for the optimal tap coefficients of DFE is carried out with the objective to minimise data jitter ...
