The filter bank multicarrier employing offset quadrature amplitude modulation (FBMC/OQAM) is a candidate transmission scheme for 5G wireless communication systems. In this project, in order to further enhance the amount of PAPR reduction, a novel pre-coding method based on a pruned Discrete Fourier Transform (DFT) in combination with one-tap scaling. The proposed technique is compared with FBMC-OQAM and SC-FBMC. The involvement of optimization techniques helps in obtaining the global best solutions. In this work, Firefly optimization algorithm (FA) is applied to pruned DFT spread. The swarm intelligence concept works on FBMC system. The results evaluate that the implemented technique i.e. FA-Pruned DFT spread having good PAPR and spectral efficiency with lower latency. The comparison of results is shown using simulated results performed in matlab.
