Timerpicker

The determination of signal arrival times has a major influence on the localization accuracy. Usually, arrival times are determined by the first threshold crossing (either fixed or adaptive). Following popular methods have been proposed in the past to automatically pick time of arrivals:

hinkley(arr[, alpha])	Hinkley criterion for arrival time estimation.
aic(arr)	Akaike Information Criterion (AIC) for arrival time estimation.
energy_ratio(arr[, win_len])	Energy ratio for arrival time estimation.
modified_energy_ratio(arr[, win_len])	Modified energy ratio method for arrival time estimation.
