【Abstract】 In this paper, the cyclostationary property of output signal of the system is discussed, when a stationary(or cyclostationary) signal passes a linear period time variant(or time invariant) system. Two kinds of time variant adaptive filter are presented, which can be used in linear period time variant system. At same time, an algorithm for period of LPTV system is also presented. Simulation results indicate the efficiency of these algorithms.更多还原
