“…In communications and radar/sonar, almost-cyclostationarity properties have been exploited for a variety of applications. They include weaksignal detection [122,123], synchronization [111,55,54], minimum mean-squared error (MMSE) filtering [115], source location [2,49,119,123,127,154,332,342], source separation [169], modulation format classification [81,327], and cognitive radio [23,144,233,329].…”
