Method for digitally modulated signals synthesis with normalized parameters
https://doi.org/10.32446/0368-1025it.2022-5-56-61
Abstract
The paper investigates the possibility of creating a calibrator of the parameters of signals with digital modulation based on an arbitrary waveform generator. A method is proposed for reproducing calibration signals with a given value of the error vector magnitude by adding a normalized distortion. A particular case of the method is considered, where amplitude and phase modulation is used as the normalized distortion. Experimental confirmation of the possibility of transferring the size of units of the modulation depth and phase deviation from the primary standards GET 166-2020 and GET 180-2010 to the calibrator of the parameters of signals with digital modulation has been obtained.
