Adaptive I/Q imbalance compensation for RF transceivers

Abstract

A novel I/Q (in-phase/quadrature) imbalance compensation scheme is proposed for quadrature-signal-mixing radio-frequency transceivers, employing either the direct-conversion architecture or the low-intermediate-frequency architecture. An adaptive DSP (digital signal processing) algorithm is developed for the proposed scheme, to on-line compensate the I/Q… (More)
