Abstract

The invention relates to a method for indirect measurement of phase delay of a RF-PWM modulator. A delay measurement system is used for measuring a phase delay of a Radio Frequency-Pulse Width Modulated (RF-PWM) signal introduced in a Radio Frequency-Pulse Width Modulator, wherein the RF-PWM signal comprises a sampling frequency and at least one carrier period, and wherein the RF-PWM signal has a symbol in the at least one carrier period. The delay measurement system comprises a first phase modulator circuit configured to generate a first Binary Phase Shifted (BPS) signal having a first period and a second period based upon the RF-PWM signal, wherein the first period of the BPS signal has the symbol therein and the second period of the BPS signal has a 180 degree inverted version of the symbol. The delay measurement system further comprises a second phase modulator circuit configured to generate a second Binary Phase Shifted (BPS) signal having a first period and a second period, wherein the first period of the BPS signal has the symbol therein and the second period of the BPS signal has a 180 degree inverted version of the symbol. Further, the delay measurement system comprises a detector circuit configured to determine the phase delay of the RF-PWM signal based on the first BPS signal or the second BPS signal and output 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...
