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

Loudness Adaptation with Modulated Stimuli [PDF]
Acta 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.

Attentional modulation of adaptation in V4 [PDF]
European 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

Adaptive Wavelet Packet Modulation [PDF]
IEEE 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 ...

Adaptive Modulation with Impulsive Interference
CoRR, 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 ...

Spectral efficiency of adaptive OFDM systems over high mobility Nakagami-m fading channels
Systems Science & Control Engineering, 2020 In this paper, we investigate the impact of rate and power adaptation (RPA) and rate adaptation (RA) using square M-ary quadrature amplitude modulation (MQAM) on the average spectral efficiency (ASE) of orthogonal frequency division multiplexing (OFDM ...

On the Adaptive Modulation for User-Centric Cell-Free Massive MIMO Systems
IEEE AccessThe cell-free (CF) systems are a key technology for future wireless networks, which exploit the scenario spatial macro-diversity to offer high channel capacity and link reliability, uniform user quality of service (QoS), and better coverage.
