This paper proposes a novel channel estimation technique for the offset quadrature amplitude modulation based filter bank multi-carrier (FBMC/OQAM) systems. Unlike the conventional approaches, the proposed pilot signals utilize their intrinsic interference for the channel estimation, and provide an improved power efficiency compared to the conventional auxiliary pilot method. However, due to the non-whiteness...
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)...
