A Concept of Synchronous ADPLL Networks in Application to Small-Scale Antenna Arrays
In this paper, we introduce a reconfigurable oscillatory network that generates a synchronous and distributed clocking signal. We propose an accurate model of the network to facilitate the study of its design space and ensure that it operates in its ...

Evaluation of Adaptive Loop-Bandwidth Tracking Techniques in GNSS Receivers
Global navigation satellite system (GNSS) receivers use tracking loops to lock onto GNSS signals. Fixed loop settings limit the tracking performance against noise, receiver dynamics, and the current scenario. Adaptive tracking loops adjust these settings

Optimum digital phase-locked loops
The optimum discrete filters to track phase and frequency steps in the presence of additive white Gaussian noise are derived, and are found to be equivalent to the baseband models of 1st- and 2nd-order digital phase-locked loops, respectively. Practical design parameters are presented.

Analysis and equalization of data-dependent jitter [PDF]
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.

Acoustic Backscatter Communication and Power Transfer for Batteryless Wireless Sensors
Sensors for industrial and structural health monitoring are often in shielded and hard-to-reach places. Acoustic wireless power transfer (WPT) and piezoelectric backscatter enable batteryless sensors in such scenarios.
