Résumé: The Filter Bank Multi-Carrier with Offset Quadrature Amplitude Modulation has already gained popularity as one of the alternatives to OFDM for next generation beyond 5G broadband wireless access systems. Like any other multicarrier modulation technique, FBMC is prone to non-linear (NL) effects of high power amplifier (HPA). Then, it is essential to mitigate NL effects to achieve energy efficiency radio communications. This paper focuses on HPA linearization, and proposes a novel adding signal based digital predistortion with a quasi-optimal convergence rate. The simulation results show that proposed technique can quickly linearize the HPA.
