Abstract
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.
