Abstract The report demonstrates the efficiency of the new theory and presents important application areas where cyclostationarity signal processing is compulsory. This short overview presents only the basic definitions of the fraction-of-time probabilistic model, the second-order cyclic autocorrelation function and the spectral correlation density function. The effect of the linear time-invariant transformations and periodic time sampling operations on the cyclostationary signals is outlined. Among the application examples, signal detection, parameter estimation of communication signals and possible exploitation of cyclic features in synchronization problems are discussed. The noise immunity of the cyclic system identification algorithms is argued and different methods are presented using the cyclic spectral correlation properties. For blind equalization of digital communication channels, both the frequency and the time domain algorithms are described. Finally, the basic properties of polyperiodic time-variant filtering are presented.
