摘要：
Previous work [1] on I/Q imbalance in SC-FDE transceivers investigates the effect of receiver I/Q imbalance but does not consider Doppler effects due to mobility. SC-FDE in doubly-selective channels is studied in (2] and [3) but without considering I/Q imbalance. In this paper, we derive an equivalent channel model for SC-FDE in the presence of both joint Tx/Rx I/Q imbalance and mobility and present an effective low-complexity digital baseband compensation scheme. Furthermore, we propose a novel joint channel and I/Q imbalance parameter estimation scheme for SC-FDE transceivers.
