Abstract
Systems and methods are provided for performing noise filtering of a received signal. A first antenna is configured to capture a first signal. A second antenna is configured to capture a second signal, desired signal arrives at the two antennas at about the same time, where noise received from directions other than the expected signal direction is received at the first antenna and the second antenna at different times. A signal processor is configured to generate a averaged signal based on the first signal and the second signal, subtract the averaged signal from the first signal to generate a noise indicating signal, perform a phase adjustment on the averaged signal based on the noise indicating signal, and subtract the phase adjusted signal from the first signal to adjust the noise indicating signal. The noise indicating signal is filtered and then subtracted from the averaged signal to generate a filtered output signal.
