Amplitude estimation of a signal with known waveform in the presence of steering vector uncertainties [PDF]

open access: yes, 2005
In this correspondence, we address the problem of estimating the amplitude of a signal with known waveform received on an array of sensors and we consider the case where there exist uncertainties about the spatial signature of the signal of interest ...

Enhanced Hybrid TIM-TDMA to Maximize the Total Throughput With Fairness Constraints

open access: yesIEEE Open Journal of the Communications Society
This paper addresses the problem of topological interference management (TIM) in ad hoc networks operating under a frequency-flat Rayleigh fading channel in single-input single-output (SISO). Assuming that the nodes have access to the statistical channel

Duration of Purkinje cell complex spikes increases with their firing frequency

open access: yesFrontiers in Cellular Neuroscience, 2015
Climbing fiber (CF) triggered complex spikes (CS) are massive depolarization bursts in the cerebellar Purkinje cell, showing several high frequency spikelet components (±600 Hz). Since its early observations, the CS is known to vary in shape.
