Searching for flickering statistics in T CrB [PDF]
, 2009 We analyse V-band photometry of the aperiodic variability in T CrB. By applying a simple idea of angular momentum transport in the accretion disc, we have developed a method to simulate the statistical distribution of flare durations with the assumption ...

Cramer-Rao bounds in the estimation of time of arrival in fading channels [PDF]
, 2018 This paper computes the Cramer-Rao bounds for the time of arrival estimation in a multipath Rice and Rayleigh fading scenario, conditioned to the previous estimation of a set of propagation channels, since these channel estimates (correlation between ...
