ABSTRACT:
The present invention discloses a beam-forming method for realizing interference suppression, comprising steps of: a. performing channel estimation for an expected user signal and interference signal in signals received by an array antenna and obtaining array channel impulse responses of the expected user signal and the interference signal respectively; b. obtaining array correlation matrixes of the expected user signal and the interference signal respectively according to the array channel impulse responses obtained in step a; c. obtaining a new array correlation matrix of the interference signal according to relation between the expected user signal with the interference and noise; and d. computing a beam-forming weighting coefficient of the array antenna according to the array correlation matrix of the expected user signal obtained in step b and the new array correlation matrix of the interference signal obtained in step c. According to this method, strong interference signals can be suppressed and the direction of the formed beam will not deviate.
