发明名称 SYSTEM AND METHOD FOR IQ IMBALANCE ESTIMATION
摘要 A system for IQ balance estimation is disclosed and may include requesting an in-phase and quadrature (IQ) probe comprising tones, receiving the tones with a frequency separation between images of the tones, the frequency separation being a result of a frequency shift at a requestor of the IQ probe, and calculating an estimate of IQ imbalance for each received tone. The system may also include requesting an IQ probe, receiving the tones with a frequency separation, and calculating an estimate of IQ imbalance for each received tone by determining an image to tone ratio based on the received tones. The requesting of the IQ probe, the receiving of the tones, and the calculating of the image to tone ratio may be repeated the results of the calculations of the image to tone ratio may be averaged. Gain, phase, and delay parameters may be calculated to compensate for the IQ imbalance.
