The compensa- tion performance depends on how accurately the adaptive equalizer coefficients can converge to the ideal values. 6. ... necessar y to enable a high data rate com- munication. It is shown that very large IQ imbalance values can be corrected just as easily. Thus the presented IQ mit- igation algorithm...
