This paper presents a new method, named as the variability method, to estimate the cyclo-period of a discrete-time cyclostationary signal. The method is essentially based on the time-varying correlation and/or mean, whose estimators are associated with some statistics of blocked signals; a plot of variability of these statistics as a function of the blocking operator index visually reveals a periodic pattern, from which the cyclo-period is obtained. The variability method is validated via simulation and real-life examples.
