RECEIVER IQ PATH IMBALANCE COMPENSATION METHOD, APPARATUS, AND DEVICE

摘要

The present application relates to the technical field of communications, and discloses a receiver IQ path imbalance compensation method, apparatus, and device. The compensation method comprises: when receiving a signal to be compensated, enabling the signal to be compensated to send a cosine signal and a sine signal by means of a signal generator that can configure a waveform amplitude and a phase, and respectively configuring that the signals are transferred on IQ paths, the cosine signal and the sine signal passing through an up converter and then looping back to a signal receiving direction; calculating autocorrelation values of the IQ paths in the signal receiving direction; determining, according to the autocorrelation values, an amplitude comparison result of the cosine signal and the sine signal that are respectively received by the IQ paths; calculating, according to the amplitude comparison result, an adjustment compensation value of an analog-domain gain amplifier and amplitude and phase values to be compensated in a digital domain; and performing compensation adjustment on the signal to be compensated according to the calculated adjustment compensation value, amplitude value, and phase value.
