Claim 5:
6. The method according to claim 5, wherein determining, for each null-steering angle based on the directivity pattern gain and the suppression multiple that correspond to the each null-steering angle, the cancellation directivity pattern gain corresponding to the each null-steering angle comprises:
for the each null-steering angle, determining a cancellation directivity pattern weight matrix P based on the first directivity pattern gain matrix A, a second directivity pattern gain matrix B, and the suppression multiple corresponding to the each null-steering angle; and
determining the cancellation directivity pattern gain corresponding to the each null-steering angle based on the cancellation directivity pattern weight matrix P;
wherein the second directivity pattern gain matrix B is the following matrix:, B
