Systemes de modulat ion et demodulation multidimensionnelle [PDF]
, 1987 Le présent exposé est consacré à la conception et à l'étude de systèmes de transmission où les symboles utilisés sont pris dans un espace à plus de deux dimensions (typiquement , 4 ou 8 dimens ions).

VIEW, EarlyView.In this work, we develop submicron‐resolution mapping of intracellular lipid elements (SMILE) as an extraction‐free vibrational spectroscopic imaging platform based on hyperspectral stimulated Raman scattering microscopy with a spectral analysis pipeline for pixel‐resolved lipid profiling.

Development and Study of Demodulation Techniques for Frequency Manipulated Signals
Известия высших учебных заведений России: Радиоэлектроника, 2017 The goal of our research is development and study of different demodulation techniques for a frequency shift keyed signals. The signal under study is a frequency-shift keyed (FSK) signal when the information signal regulates the carrier frequency.

Satellite Signal Demodulation Using Kalman Filter [PDF]
, 2017 Satelitski komunikacijski sustavi koriste QPSK demodulaciju u svrhu rekonstrukcije poslanog signala. Signal koji dolazi na prijamnik, prolaskom kroz AWGN kanal, podložan je utjecaju Gaussovog bijelog šuma.

High Voltage, EarlyView.ABSTRACT The detection of partial discharges (PD) on the power transformer tank demands higher sensitivity in ultrasonic detection. To target the detection frequency band for sensor optimisation and enhance sensitivity, this paper presents a dual‐frequency sensitivity model for optical fibre ultrasonic sensors.

Topics in Multi dimensional Signal Demodulation [PDF]
, 2001 Problems in the demodulation of one, two, and three-dimensional signals are investigated. In one-dimensional linear systems the analytic signal and the Hilbert transform are central to the understanding of both modulation and demodulation. However, it is

British Journal of Psychology, EarlyView.Abstract The AI revolution has produced synthetic faces that often appear more human than photos of real people. We tested whether individual differences in human face recognition ability explain variation in discriminating AI from real faces. Super‐recognizers – people with exceptional ability to recognize human faces (N = 36) – outperformed a typical

Werner Irnich: Pioneer in the Development of the Dual‐Chamber Pacemaker—An Obituary
Pacing and Clinical Electrophysiology, EarlyView.ABSTRACT Fifty years ago, Werner Irnich presented the concept of an optimal pacemaker capable of responding appropriately to various cardiac arrhythmias and perceptual disturbances, and intended to be used in 85% of patients. With this concept, Irnich was far ahead of his time. His proposed circuitry for AV block and atrial fibrillation, as well as his

Plant Breeding, EarlyView.ABSTRACT In animal‐pollinated plants, pollen dispersal depends on several plant and animal characteristics that can influence the paternal success of a plant. Paternal success affects the genetic contribution of a genotype to the next generation, which is relevant to plant breeding.

Application of microwave six-port in software radio
Tongxin xuebao, 2005 Common formulas of six-port demodulation orthogonal modulation signals was educed. The results of simulation in demodulation QPSK, 16QAM, π/4QPSK modulation signals are well agreement with the theory analysis.
