Abstract :
A new technique of separating jamming from signal is studied in this paper. The signal separation can be accomplished by employing the time correlation and the spectral correlation. The structure of blind adaptive frequency-shift filtering is proposed and the variable step-size adaptive algorithm is introduced. Finally the separation performance of variable step-size BA-FRESH filters is analyzed at the different jamming through computer simulations. This separation technique is thus very attractive for communication anti-jamming.
