Research on Multi-Peak Detection of Small Delay Spoofing Signal [PDF]

IEEE Access, 2020
With the widespread application of GNSS systems in various fields, the problem of spoofing detection has drawn much attention from the satellite navigation community. The GNSS spoofing interference generally uses fake or replayed satellite signals to make the targeted receivers receive false GNSS signals and reduce the accuracy of calculated position ...

Pulse Peak Delay-Total Focusing Method for Ultrasonic Tomography on Concrete Structure

Applied Sciences (Switzerland), 2021
An ultrasonic array device like the A1040 MIRA is used to non-destructively visualize the inside of concrete structures. A data set acquired by the ultrasonic array device is so unfocused that an image reconstruction algorithm is required to transform ...

Peak Delay in Persian Intonational Phonology: Phonetic or Phonological? [PDF]

مطالعات زبان‌‌ها و گویش‌های غرب ایران, 2019
There are two competing views with respect to the tonal structure of Persian pitch accents. According to the first view, peak delay in Persian intonational grammar serves no phonological or contrastive function. This view assumes that the earlier or later peak alignment in Persian does not lead to contrasts in intonational meanings.

Noninvasive blood pressure estimation with peak delay of different pulse waves [PDF]

International Journal of Distributed Sensor Networks, 2019
In this article, we discuss the validity of noninvasive continuous blood pressure estimation with two different types of peripheral pulse waves. Artery-blocking experiment shows that phase difference of two pulse waves at the same location is well related with blood pressure and blood flow fluctuation.

Prosodic analysis of Ezafe construction in the framework of prosodic phonology [PDF]

زبان پژوهی, 2019
In this study, the prosodic pattern of Ezafe construction has been investigated under the framework of prosodic phonology. Prosodic phonology is a framework which evinces that a purely phonological constituent structure lies between syntax and phrasal ...

A digital delay locked loop with a monotonic delay line

Electronics Letters, 2023
This paper proposes a digital delay locked loop (DLL) with a monotonic delay line (DL). This DLL adopts the calibration mode to reduce the non‐monotonic effects for the coarse‐tuning delay line (CTDL) and the fine‐tuning delay line (FTDL).

A Low-Jitter Harmonic-Free All-Digital Delay-Locked Loop for Multi-Channel Vernier TDC

Sensors, 2021
This paper presents a low jitter All-Digital Delay-Locked Loop (ADDLL) with fast lock time and process immunity. A coarse locking algorithm is proposed to prevent harmonic locking with just a small increase in hardware resources.

Delay and Peak-Age-of-Information of ALOHA Networks With Limited Retransmissions [PDF]

IEEE Wireless Communications Letters, 2021
Esta carta analiza el impacto de las retransmisiones de paquetes en el rendimiento de los protocolos inalámbricos de acceso aleatorio. En particular, nos centramos en los efectos de dos parámetros controlables, a saber, la velocidad a la que se producen las retransmisiones y el número de retransmisiones permitidas.

Using Machine Learning Method to Discover Hygrothermal Transfer Patterns from the Outside of the Wall to Interior Bamboo and Wood Composite Sheathing

Buildings, 2022
To identify hygrothermal transfer patterns of exterior walls is a crucial issue in the design, assessment, and construction of buildings. Temperature and relative humidity, as sensor monitoring data, were collected from the outside of the wall to ...
