Theoretical analysis of SINR performance for unsynchronized and nonlinearly distorted FBMC signals

In this paper, we present a theoretical analysis of the joint effect of carrier frequency offset (CFO) and high power amplifier (HPA) nonlinear distortion (NLD) on the signal to interference plus noise ratio (SINR) of filter bank multicarrier (FBMC) systems. A promising class of FBMC modulation, called Cosine Modulated Multitone (CMT), is considered and the analytical SINR is derived in the presence of both HPA NLD and CFO. The simulation results have shown a good agreement with the theoretical analysis. © Springer International Publishing Switzerland 2016.
