Abstract
A Radio Frequency Interference (RFI) estimation device for generating an estimated RFI signal includes a combiner, a first multiplier and a second multiplier. The combiner is configured to combine a first digital signal and a second signal to generate the estimated RFI signal. The first multiplier is configured to generate the first digital signal according to an in-phase signal and a first cosine signal. The second multiplier is configured to generate the second digital signal according to a quadrature-phase signal and a first sine signal. The first cosine signal and the first sine signal are generated based on a frequency and the in-phase signal and the quadrature-phase signal are generated based on the frequency and one or more harmonics of the frequency.
