Interference-dependent pair of pilots for channel estimation in FBMC systems

In this work, we develop a new pilot-aided channel estimation for filter bank multi-carrier (FBMC) systems. The proposed method is different from previous approaches in the sense that it uses the intrinsic interference rather than cancelling it. By doing so, we can obtain a virtual power boosting effect without increasing power budget. The estimation, detection, and peak-to-average power ratio (PAPR) performance of the proposed scheme are demonstrated through the computer simulation.
