The digital modulation quality parameters are very important technical index in digital communication system, which can indicate the figure-of-merit of digital signal modulation and assure the system running in good condition. In order to support the future parameter calibration in the digital modulation of the communication system, a basic parameter calibration method is researched. Based on building a general calibration simulation model, the method study on the parameter calibration of QPSK and FSK signals is carded out. The simulation and practice are tested well, and the effectiveness of the method is proved. The calibration simulation can reduce much hardware loss and research cost.
