I/Q timing mismatch compensation

摘要

Timing correction is affected for mismatch between channels in an I/Q demodulator. The respective demodulated I-channel and Q-channel are correlated and integrated so generate a timing control signal that is applied to a variable delay element. The variable delay element inserts a variable time delay in an ADC clock signal that is applied to either the I-channel ADC or the Q-channel ADC.
