The considered system consists of a reference mobile user perfectly synchronized with its reference base station (BS) and K interfering BSS. We have considered both synchronization errors and high power amplifiers (HPA) non linear distortions (NLD). We analyzed first the signal to noise plus interference ratio (SINR). On the basis of this analysis, derived an accurate of bit error rate (BER) in the presence of a frequency selective channel. In order to reduce the computational complexity of the BER expression, we applied an interesting lemma based on the moment generating function of the interference power.

A promising class of FBMC modulation called Cosine Modulated Multitone (CMT) will be considered. For the studied system, analytical expressions of the signal to interference ratio (SIR) and bit error rate (BER) will be derived in the presence of HPA distortions, timing errors and carrier frequency offset (CFO). To this end, we have developed a closed-form expression of interference and useful signal powers using some acceptable approximations. The proposed model is compared with existing models designed for the considered system or for other multicarrier systems like SMT (Staggered Modulated Multitone) or OFDM. {\textcopyright} Springer International Publishing AG 2017.}, doi = {10.1007/978-3-319-68179-5_48}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-85034587110\&doi=10.1007\%2f978-3-319-68179-5_48\&partnerID=40\&md5=6d16308c4170297309c0b8c954bb39aa}, author = {Elmaroud, B. and Faqihi, A. and Aboutajdine, D.} } @article {Elmaroud2017, title = {Sensitivity analysis of FBMC-based multi-cellular networks to synchronization errors and HPA nonlinearities}, journal = {Eurasip Journal on Advances in Signal Processing}, volume = {2017}, number = {1}, year = {2017}, note = {cited By 1}, abstract = {In this paper, we study the performance of asynchronous and nonlinear FBMC-based multi-cellular networks.
