Abstract
Technologies directed to correcting terrestrial interference using narrowband adaptive filtering and beamforming technology are described. One method includes receiving a first and second radio frequency (RF) signal. The method includes generating first digital samples corresponding to the first RF signal using a first sample rate and generating second digital samples corresponding to the first RF signal using a second sample rate that is lower than the first sample rate. The method further includes generating third digital samples corresponding to the second RF signal using the second sample rate. The method further includes determining parameters associated with a filtering process using the second digital samples and the third digital samples. The method further includes generating fourth digital samples using the parameters of the filtering process. The method further includes removing a first portion from the first RF signal using the first digital samples and the fourth digital samples.
