Abstract

The invention discloses a main lobe interference suppression method and device. The method includes calculating an optimal weight vector of main lobe interference according to a constraint matrix, a load electrical level, an array receive data matrix and a preprocessing block matrix; and using the optimal weight vector of main lobe interference to perform main lobe interference suppression. By means of the main lobe interference suppression method and device, main beams are enabled to point to an expected target direction, and simultaneously, main lobe interference is inhibited from forming deep null steering in other interference directions.

Description

technical field [0001] The present invention relates to the communication field, in particular to a main lobe interference suppression method and device. Background technique [0002] With the development of mobile communication, smart antenna technology is also applied in mobile communication of multi-antenna system. The smart antenna uses digital signal processing technology to generate spatially directional beams, so that the main beam of the antenna is aligned with the direction of the desired user signal, and the side lobes or nulls are aligned with the direction of the interference signal, so as to effectively receive the desired mobile user signal and suppress or eliminate the useless interference signal. . [0003] In the presence of mainlobe interference, applying conventional adaptive beamforming techniques will result in increased sidelobe levels, distortion of the main beam, and shifted peaks, thereby degrading the output SNR. When the main lobe interference is...
