Variability Method for Cyclo-period Estimation of Cyclostationary Signals

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 pe...

On detection of cyclostationary signals

This paper presents a detector for cyclostationary signals that uses an estimate of spectral autocoherence as a detection statistic. The detector's probability of false alarm is analytically derived and veriied with computer simulations. Receiver operating characteristic curves are determined from the simulation data and the analytical expression for the probability of false alarm. A detector f...

Cyclostationary Signals in Battlefield Acoustics

Cyclostationary signals are found when randomness occurs together with periodicity in a physical system. In this presentation we will show evidence of cyclostationarity in battlefield acoustic signals using algorithms that have been developed in the past 10 years. Cyclostationary signal processing may provide features that will aid in target classification and association. Introd uction 1 We be...
