Attention reinforces human corticofugal system to aid speech perception in noise
2021
NeuroImage
Active listening (but not arousal-control tasks) exaggerated both ERPs and FFRs, confirming attentional gain extends to lower subcortical levels of speech processing. ...
We varied attention with active vs. passive listening scenarios whereas task difficulty was manipulated with additive noise interference. ...
and (ii) converting each single dipole to a regional source to consider activity in all three (x, y, z) dipole orientations from each ROI. ...

Superposition network coding for wireless cooperative communication
2012
6th International Symposium on Telecommunications (IST)
Then, a cooperative strategy is proposed that improves overall communication performance in comparison with non-cooperative protocols with high spectral efficiency and non synchronization problems. ...
In this technique, we use a combination of superposition coding and network coding to achieve cooperative diversity in asymmetric wireless networks; hence the name superposition network coded cooperation ...
NTRODUCTION Speech enhancement is conventionally used as a preprocessing step in various areas of the speech processing [1] . ...

Journal of the Acoustical Society of America
A novel frequency-domain periodic active noise control algorithm with nonlinear secondary path. ...
The shielded domain is a 1mx1mx1m box with 1-3 sides open. Up to 4 control sources were used on each of the open sides to shield the domain from external noise. ...
This study examined whether 1-hour perceptual training could elicit feature-specific improvement of performance and corresponding cortical plasticity in humans during speech segregation by using magnetoencephalography ...
