Basic Modulation Schemes in Digital Mobile Multimedia Broadcasting Systems [PDF]

, 2009
Modulation is the mapping-superimposing process where the baseband bit stream message information is mapped to the radio carrier. Modulation and demodulation are paired with modulation being carried out at the transmitter, and the demodulation being ...

Optical spatial modulation with DHT-based OFDM in visible light communication systems [PDF]

, 2017
In this paper, a novel orthogonal frequency division multiplexing (OFDM) modulation scheme based on discrete Hartley transform (DHT) combined with optical spatial modulation (OSM) is proposed for visible light communication (VLC) systems. In the proposed

Envelope enhancement increases cortical sensitivity to interaural envelope delays with acoustic and electric hearing. [PDF]

, 2014
Evidence from human psychophysical and animal electrophysiological studies suggests that sensitivity to interaural time delay (ITD) in the modulating envelope of a high-frequency carrier can be enhanced using half-wave rectified stimuli.

Inter-Turn Short Circuit Detection Based on Modulation Signal Bispectrum Analysis of Motor Current Signals [PDF]

, 2013
Motor current signature analysis (MCSA) is a common practice in industry for finding motor faults. However, because of small modulations caused by faults and high noise contamination, it is difficult to quantify the modulation in measured signals which ...

Quantifying Cortical Maturational Aspects During Different Vigilance States in Preterm Infants by Advanced EEG Analysis

Journal of Sleep Research, Volume 35, Issue 4, August 2026.
ABSTRACT Preterm birth is a significant risk factor for atypical neurodevelopment, yet early electrophysiological markers of brain maturation are still lacking. Non‐invasive electroencephalographic (EEG) monitoring of cortical maturation in these patients holds promise as a tool for neurodevelopmental prediction.
