Abstract :
As a important component of communication electronic warfare, signal separation has the great effect increasingly. Although there are many kinds of technologies based on time-frequency could be used to separate signal, it is difficult to apply them to complex electromagnetism circumstance on field, for the sake of disadvantage-need to get the prior information to object signal. This paper provides a separation method for mixed modulation signals. The simulation shows it is efficient while SNR is above 5 dB.
