In this paper, we study the performance of asynchronous and nonlinear FBMC-based multi-cellular networks. The\nconsidered system includes a reference mobile perfectly synchronized with its reference base station (BS) and K\ninterfering BSs. Both synchronization errors and high-power amplifier (HPA) distortions will be considered and a\ntheoretical analysis of the interference signal will be conducted. On the basis of this analysis, we will derive an\naccurate expression of signal-to-noise-plus-interference ratio (SINR) and bit error rate (BER) in the presence of a\nfrequency-selective channel. In order to reduce the computational complexity of the BER expression, we applied an\ninteresting lemma based on the moment generating function of the interference power. Finally, the proposed model\nis evaluated through computer simulations which show a high sensitivity of the asynchronous FBMC-based\nmulti-cellular network to HPA nonlinear distortions.
