%X The main methods for estimation of cyclic spectra for cyclostationary processes are temporally smoothed cyclic periodogram and spectrally smoothed cyclic periodogram. In case of short record length, both methods have low resolution and reliability. This paper uses two-channel complex maximum entropy (autoregressive) spectral analysis method to estimate cyclic spectra. Fine performances such as resolution and reliability can be obtained with this method.
