A Novel FBMC/QAM Scheme to Eliminate the Error Floor in Multipath Channels
IET Communications, Volume 19, Issue 1, January/December 2025.This paper proposes a cyclic prefix–based filter bank multicarrier with quadrature amplitude modulation (CP‐FBMC/QAM) scheme to eliminate the error floor and simplify the receiver in multipath fading channels. Moreover, to avoid the increase of out‐of‐band (OOB) radiation caused by the CP insertion, we propose a prototype filter optimization problem ...
