| Abstract: | This paper brings forth a new idea about integrating interference localization and adaptive nulling techniques against uplink radio frequency interference, which causes severe degradation on the performance of satellite communication system. Spatial spectrum estimation approaches, in conjunction with Multiple Beam Antenna (MBA), are first employed for accurate source localization. This estimated DOA information is then used to achieve adaptive interference suppression. Simulation results with high resolution MUSIC algorithm show that the scheme is feasible. |
