Abstract
The Doppler signal processing device includes a frequency analyzer, an interference suppressor, an interference baseline estimator and a synthesizer. The frequency analyzer can generate a frequency domain signal according to a digital signal. The interference suppressor can perform a suppression operation to generate an interference suppressed frequency domain signal. The interference baseline estimator can generate or update the frequency domain interference estimation signal according to the frequency domain signal. The synthesizer can generate an interference suppressed digital signal according to the interference suppressed frequency domain signal, where the interference suppressed digital signal is related to the digital signal with the interference energy suppressed.
