In order to improve the quality of the navigation signal in the Beidou global navigation system,a calibration and compensation algorithm for the distortion characteristic of the modulator is proposed.First of all,we analyze the distortion characteristics of the modulator; on this basis,we study the effects of the distortion characteristics of navigation signal quality through mathematical derivation and simulation experiments; and then we proposes a modulator distortion characteristic calibration and compensation algorithm,through actual modulator test,verify the validity of the methods.
