http://dbpedia.org/ontology/abstract A cyclostationary process is a signal haviA cyclostationary process is a signal having statistical properties that vary cyclically with time.A cyclostationary process can be viewed as multiple interleaved stationary processes. For example, the maximum daily temperature in New York City can be modeled as a cyclostationary process: the maximum temperature on July 21 is statistically different from the temperature on December 20; however, it is a reasonable approximation that the temperature on December 20 of different years has identical statistics. Thus, we can view the random process composed of daily maximum temperatures as 365 interleaved stationary processes, each of which takes on a new value once per year. which takes on a new value once per year. , Un processo ciclostazionario è un segnale Un processo ciclostazionario è un segnale avente proprietà statistiche che variano nel tempo.I processi stocastici ciclostazionari servono per descrivere processi generati da fenomeni periodici, come ne esistono molti in natura. Tali processi, sebbene non siano descritti in termini di funzioni periodiche del tempo, producono dati che possono essere descritti attraverso parametri statistici che variano periodicamente nel tempo (statistiche di primo e secondo ordine). Ad esempio, nelle telecomunicazioni, la periodicità dei dati è dovuta alla modulazione, al campionamento, alla codifica; in meccanica è dovuta alla rotazione dei meccanismi, mentre in radioastronomia la periodicità è generata ad esempio dai moti di rotazione e rivoluzione dei pianeti e dalla pulsazione delle stelle.i pianeti e dalla pulsazione delle stelle.
