ABSTRACT

In this work, we present an adaptive non-data-aided compensator for the in-phase/quadrature-phase (I/Q) mismatch in low-intermediate frequency (heterodyne) receivers. In particular, the adaptive I/Q mismatch algorithm is derived by exploiting the uncorrelatedness between the desired and the image signals, and is used to compensate for gain imbalance and phase-offset error. Furthermore, the frequency-offset error is separately compensated by using an adaptive minimization of a fourth-order statistics based cost function.
