Implicit Adaptation Is Modulated by the Relevance of Feedback [PDF]

open access: yesJournal of Cognitive Neuroscience, 2022
Abstract Given that informative and relevant feedback in the real world is often intertwined with distracting and irrelevant feedback, we asked how the relevancy of visual feedback impacts implicit sensorimotor adaptation. To tackle this question, we presented multiple cursors as visual feedback in a center-out reaching task and ...

Does Fast Adaptive Modulation Always Outperform Slow Adaptive Modulation? [PDF]

open access: yesIEEE Transactions on Wireless Communications, 2011
Link adaptation techniques are important modern and future wireless communication systems to cope with quality of service fluctuations in fading channels. These techniques require the knowledge of the channel state obtained with a portion of resources devoted to channel estimation instead of data and updated every coherence time of the process to be ...

Attentional modulation of adaptation in V4 [PDF]

open access: yesEuropean Journal of Neuroscience, 2009
AbstractAdaptation and visual attention are two processes that alter neural responses to luminance contrast. Rapid contrast adaptation changes response size and dynamics at all stages of visual processing, while visual attention has been shown to modulate both contrast gain and response gain in macaque extrastriate visual cortex. Because attention aims

Loudness Adaptation with Modulated Stimuli [PDF]

open access: yesActa Acustica united with Acustica, 2015
© S. Hirzel Verlag • EAA. At low sensation levels, loudness adaptation is described as a decrease in loudness judgment over time of a steady, fixed-intensity auditory stimulus, presented monaurally. Similarly, at high sensation levels, loudness enhancement is described as an increase in loudness judgment over time.

MIMO Systems With Adaptive Modulation

open access: yesIEEE Transactions on Vehicular Technology, 2005
Adaptive modulation (AM) schemes in multiple input multiple output (MIMO) systems with a perfect or imperfect channel state information (CSI) at both the transmitter and receiver were investigated. Under an average transmit power and instantaneous bit error rate (BER) constraint, the transmit parameters including the subchannel transmit power and/or ...

Adaptive Wavelet Packet Modulation [PDF]

open access: yesIEEE Transactions on Communications, 2018
In this paper, we propose a new adaptive modulation based on the wavelet packet transform, which targets a good resistance against frequency selective channels while avoiding a large PAPR. Classical multi-carrier modulation schemes divide the channel bandwidth into narrowband sub-channels to improve its robustness against frequency selective fading ...

Multiple treg suppressive modules and their adaptability [PDF]

open access: yesFrontiers in Immunology, 2012
Foxp3(+) regulatory T cells (Tregs) are a constitutively immunosuppressive cell type critical for the control of autoimmunity and inflammatory pathology. A range of mechanisms of Treg suppression have been identified and it has not always been clear how these different mechanisms interact in order to properly suppress autoimmunity and excessive ...

Channel-Adaptive Modulation [PDF]

open access: yes6th International Conference on Radio Receivers and Associated Systems, 1995
Packet Reservation Multiple Access (PRMA) assisted adaptive modulation suing 1,2 and 4 bit/symbol transmissions is proposed as an alternative to Dynamic Channel Allocation (DCA) in order to maximise the number of users supported in a traffic cell. The cell is divided in three concentric rings and in the central high Signal-to-Noise ratio (SNR) region ...

Adaptive Modulation with Impulsive Interference

open access: yesCoRR, 2016
In this letter, we analyze power and rate adaptation in a point-to-point link with Rayleigh fading and impulsive interference. We model the impulsive interference as a Bernoulli-Gaussian random process. Adaptation is used to maximize the average spectral efficiency by changing power and rate of the transmission subject to an average power and ...
