Method for measuring power of non-constant envelope modulated signal, and electronic device

A method for measuring a power of a non-constant envelope modulated signal, the method comprising:

• sampling baseband in-phase and quadrature (I/Q) data transmitted by a device under test to obtain sample baseband I/Q data, wherein a sampling duration is less than a length of a cycle of the non-constant envelope modulated signal;
• decoding the sample baseband I/Q data to obtain sample binary data;
• calculating a sample power within the sampling duration based on the sample baseband I/Q data;
• matching in binary data transmitted by a transmitter of the device under test based on the sample binary data to obtain a target binary data segment;
• obtaining a power calibration value corresponding to the target binary 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 binary data segment and the sample power within the sampling duration.

An electronic device comprising:

• a processor;
• and
• a memory for storing instructions executable by the processor;
• wherein the processor is configured, executing the instructions, to:
• sample baseband in-phase and quadrature (I/Q) data transmitted by a device under test to obtain sample data, wherein a sampling duration is less than a length of a cycle of a non-constant envelope modulated signal;
• calculate a sample power within the sampling duration based on the sample data;
• match in predetermined baseband I/Q data in the cycle based on the sample data to obtain a target baseband I/Q data segment;
• obtain a power calibration value corresponding to the target baseband I/Q data segment;
• and
• obtain 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.
