Abstract

In this work, a cost-effective radio frequency (RF) beamforming array is used to orient and suppress directional interfering signals. With this frontend, both the multiple signal classification (MUSIC) algorithm used in direction-of-arrival (DOA) estimation and the optimizaoion based power inversion (PI) algorithm used to suppress the interfering signal can be significantly simplified. With a RF output, the proposed frontend can be directly connected to existing receivers with RF inputs. Simulations and experiments of a 5-element linear array verified the effectiveness of the proposed approach, showing the potential in practical applications.
