Abstract: The communication receiver comprises a mixer being configured to mix the communication signal with a periodic mixing signal having a mixing frequency fC to obtain a mixed communication signal, wherein the mixed communication signal comprises a first frequency spectrum portion comprising the spectral region of interest being situated around a frequency fRF+fC and a second frequency spectrum portion comprising the spectral range of interest being situated around fRF−fC; a first demodulator being configured to demodulate a first frequency channel of the plurality of frequency channels within the spectral range of interest of the first frequency spectrum portion on the basis of a first local oscillator frequency fLO1; and a second demodulator being configured to demodulate a second frequency channel of the plurality of frequency channels within the spectral region of interest of the second frequency spectrum portion on the basis of a second local oscillator frequency fLO2.
