Abstract

In this paper, we address the joint estimation of the channel impulse response and frequency-dependent in-phase and quadrature-phase (I/Q) imbalances using data-dependent superimposed training (DDST). The analysis developed shows that it is possible to use the first-order statistics of the received process to achieve synchronization and identify the resulting widely linear system that encompasses the radio frequency impairments considered. Furthermore, it is also verified that for the joint estimation of the transmitter and the receiver I/Q imbalances, additional constraints than those required for strictly linear systems should be imposed on the training sequences employed. The results of numerical simulations show that DDST has comparable performance with methods reported in the literature.
