摘要

Filter bank multi-carrier (FBMC) is considered a promising alternative to the Orthogonal Frequency Division Multiplexing (OFDM) scheme. It improves spectral efficiency by eliminating the need for cyclic prefix while attenuating interference due to the robustness of the out-of-band emission. In this work, we present a framework, and the performance evaluation of FBMC is a multi-carrier modulation scheme for the direct detection of optical communications. As the proposed model has higher spectral efficiency than the classical ACO-OFDM, as removing the guard interval enhances the spectral efficiency. Furthermore, the perfect rectangular pulse shaping and eliminating the out of band emission of the filter bank enhances the ACO-FBMC the BER performance of the ACO-OFDM. We propose a transceiver model for Asymmetrical Clipped Optical FBMC (ACO-FBMC) based on Fast Fourier Transform (FFT) operations, analyze inter-frame interference, and offer an iterative receptive method to eliminate it. Finally, we compared the bit error rate (BER) performance of the ACO-FBMC using different overlapping factors with the ACO-OFDM.
