An integrated multi-user satellite receiver includes: a single-chip, and the single-chip includes: a first synthesizer for generating a first oscillating signal having a first frequency; a first frequency multiplier for generating a second oscillating signal having a second frequency according to the first oscillating signal; a second synthesizer for generating a third oscillating signal having a third frequency; and a second frequency multiplier for generating a fourth oscillating signal having a fourth frequency according to the third oscillating signal; wherein the single-chip generates a first down-converted signal according to a first satellite signal and the second oscillating signal, generates a second down-converted signal according to the first satellite signal and the fourth oscillating signal, generates a third down-converted signal according to a second satellite signal and the second oscillating signal, and generates a fourth down-converted signal according to the second satellite signal and the fourth oscillating signal.

The present disclosure provides a method and apparatus for adjusting a harmonic parameter, a processor and an electronic device. The method includes: a target signal is determined, and the target signal is a communication signal by means of which a processor of a device interacts with other devices at present; a plurality of harmonics corresponding to a plurality of chips are determined, and whether a target harmonic present in the plurality of the harmonics is determined, and the target harmonic is a harmonic interfering with the target signal, and the plurality of the chips exist in the device; and in a case that the target harmonic is present, the harmonic parameter of the target harmonic is adjusted to a target harmonic parameter.
