Described herein is a baseband circuit and a method of operation thereof for use in a GNSS receiver to mitigate jamming and other interference. The baseband circuit may include a time-domain interference mitigation (TDIM) circuit and a frequency-domain interference mitigation circuit (FDIM) for each of multiple RF paths. The TDIM circuit may include a set of notch filters. A processor coupled with the baseband circuit may compute a direct Fourier transform of digital samples of received satellite signals, generate a set of control parameters based on the DFT of the digital samples, and adjust the TDIM and FDIM circuits using the set of control parameters. The set of control parameters may include filter coefficients for the set of notch filters to reject multiple narrow-band interferers.
