Abstract :
This paper focuses on the digital beamforming application. An adaptive spatial smoothing method is proposed. Compared with the traditional uniform spatial smoothing method, the advantages of this method are. (1) When the incident angles between interferers and desired signal are small, the array gain is improved. (2) When large subarray aperture is required, the adaptive spatial smoothing method can provide better array gain.
