Binarized Brain Connectivity: A Novel Autocorrelation-Based Iterative Synchronization Technique

open access: greenIEEE Transactions on Signal and Information Processing over Networks, 2017
The brain is a highly interconnected neurobiological system. Network-level characterization is thus largely performed to understand brain functioning. Brain activity can be captured through modalities like functional magnetic resonance imaging (fMRI) and electroencephalogram (EEG).

Two-Dimensional Wavenumber Analysis Implemented in Ultrasonic Vector Doppler Method with Focused Transmit Beams

open access: yesSensors, 2022
The multi-angle Doppler method was introduced for the estimation of velocity vectors by measuring axial velocities from multiple directions. We have recently reported that the autocorrelation-based velocity vector estimation could be ameliorated ...

Blind CP-OFDM and ZP-OFDM Parameter Estimation in Frequency Selective Channels

open access: yesEURASIP Journal on Wireless Communications and Networking, 2009
A cognitive radio system needs accurate knowledge of the radio spectrum it operates in. Blind modulation recognition techniques have been proposed to discriminate between single-carrier and multicarrier modulations and to estimate their parameters. Some

Complete characterization of ultrafast optical fields by phase-preserving nonlinear autocorrelation

open access: yesLight: Science & Applications, 2022
We introduce and experimentally demonstrate a novel technique for the complete characterization of ultrafast optical fields based on phase-preserving nonlinear interferometric autocorrelation without any spectroscopic measurements.

Blind Coarse Timing Offset Estimation for CP-OFDM and ZP-OFDM Transmission over Frequency Selective Channels

open access: yesEURASIP Journal on Wireless Communications and Networking, 2009
We present a blind coarse timing offset estimation technique for CP-OFDM and ZP-OFDM transmission over frequency selective channels. The technique exploits the cyclic prefix or zero-padding structure to estimate the starting position of the OFDM symbols ...
