Abstract
The disclosure provides a method for measuring a power of a non-constant envelope modulated signal, an electronic device, and a computer readable storage medium. The method includes: sampling baseband I/Q data transmitted by a device under test to obtain sample data, in which a sampling duration is less than a length of a cycle of the non-constant envelope modulated signal; calculating a sample power within the sampling duration based on the sample data; matching in predetermined baseband I/Q data in the cycle based on the sample data to obtain a target baseband I/Q data segment; obtaining a power calibration value corresponding to the target baseband I/Q data segment; and obtaining an actual power of the non-constant envelope modulated signal in the cycle based on the power calibration value corresponding to the target baseband I/Q data segment and the sample power within the sampling duration.
