Network coded modulation for two-way relaying [PDF]
, 2011 Network coding compresses multiple traffic flows with the aid low-complexity algebraic operations, hence holds the potential of significantly improving both the power and bandwidth efficiency of wireless networks.

Amplitude modulation of radiation by coupled resonators
Доклады Белорусского государственного университета информатики и радиоэлектроники, 2020 In this paper, we describe a method that allows one to realize highly efficient amplitude modulation of radiation at the output of electro-optical laser switches with two coupled resonators, in which electro-optical elements are located both in two split

Amplitude modulation in δ Sct stars: statistics from an ensemble study of Keplertargets [PDF]
, 2016 We present the results of a search for amplitude modulation of pulsation modes in 983 δ Sct stars, which have effective temperatures between 6400 ≤ Teff ≤ 10 000 K in the Kepler Input Catalogue and were continuously observed by the Kepler Space Telescope

Method for assessing the amplitude modulation of the stationary planetary waves [PDF]
Annales Geophysicae, 2009 This short-communication presents a new method for assessing the amplitude modulation of the stationary planetary waves (SPWs). The suggested procedure allows estimating the contribution of the amplitude modulated SPWs to the field of the zonally ...

Amplitude Modulation and Loudness in Cochlear Implantees [PDF]
Journal of the Association for Research in Otolaryngology, 2009 The effect of amplitude modulation of pulse trains on the loudness perceived by cochlear implantees was investigated for different overall levels of the signal, modulation depth and the carrier rate of the pulse train. Equally loud and threshold levels were determined for a variety of signal levels, modulation depths and carrier rates in six cochlear ...

On the Impact of Amplitude Variation on Interpolated DFT Method and How to Reduce It
Elektronika ir Elektrotechnika, 2018 The Interpolated DFT is often used to improve frequency estimation of the spectral lines of DFT’s spectrum. If the measured spectral line is distorted the accuracy of Interpolated DFT is decreased. Such distortion could be a result of amplitude variation

Semi-blind adaptive beamforming for high-throughput quadrature amplitude modulation systems
, 2010 A semi-blind adaptive beamforming scheme is proposed for wireless systems that employ high-throughput quadrature amplitude modulation signalling. A minimum number of training symbols, equal to the number of receiver antenna arrays elements, are first ...
