Estimation and Compensation of CFO and I/Q Imbalance in OFDM Systems Under Timing Ambiguity

Abstract

This paper proposes a joint carrier frequency offset (CFO) and In-phase/Quadrature-phase (I/Q) imbalance estimation and compensation method for orthogonal frequency-division-multiplexing (OFDM) systems under timing uncertainty. A matrix representation of the received signal with CFO, timing offset (TO), and I/Q imbalance is first derived. Then, a least… (More)
