摘要: A system and method are provided for calibrating the IQ-imbalance in a low-IF receiver. Test Signal can be generated mirror frequency conveyed to The power of signal produced receiver from measured. In absence an IQ-imbalance, completely eliminated corresponding measured minimized. Accordingly, two dimensional algorithm is described correcting by adjusting phase gain difference between I Q channels based on
