Abstract

The present disclosure relates to a method for the indirect measurement of the phase delay of an RF-PWM modulator. The delay measurement system is used to measure the phase delay of an RF-PWM signal introduced in an RF-PWM modulator, wherein the RF-PWM signal comprises a sampling frequency and at least one carrier period in which the RF-PWM signal has symbols. The delay measurement system comprises: a first phase modulator circuit generating a first BPS signal having a first period and a second period based on an RF-PWM signal, the first period of the BPS signal having said symbol therein and the BPS signal The second period of has a 180-degree inverted version of the symbol; a second phase modulator circuit, generating a second BPS signal having a first period and a second period, the first period of the BPS signal having the symbol in it and the second period of the BPS signal has a 180 degree inverted version of the sign; a detector circuit, determining a phase delay of the RF-PWM signal based on the first BPS signal or the second BPS signal and outputting the phase delay.

Description

technical field [0001] The present disclosure relates to a phase delay measurement system and a method for measuring phase delay in a communication system. Background technique [0002] A digital radio-frequency-pulse-width modulation (RF-PWM) modulator is used to perform direct digital up-conversion from baseband to radio frequency (RF). The output signal remains fully binary. Non-ideal digital and analog effects of the RF-PWM modulator can affect the quality of the output leading to erroneous results. Therefore, non-ideal digital and analog effects need to be compensated. To compensate for these effects, it may be necessary to know the precise phase delay of the output signal relative to the sampling timing. Contents of the invention [0003] The purpose of this disclosure is to provide a scheme for measuring the phase delay of an RF-PWM modulator. [0004] According to an aspect of an embodiment of the present disclosure, a delay measurement system is provided for m...
