Abstract :
In this sequel to [1], the joint Tx/Rx I/Q imbalance model of mobile SC-FDE transceivers is extended to include the effect of residual carrier frequency offset. Furthermore, the equivalent channel model for multiple-antenna spatially-multiplexed SC-FDE transceivers in the presence of I/Q imbalance and mobility is derived and an effective digital baseband compensation scheme is proposed, and its performance is evaluated including the effects of channel estimation.
