Analysis of Pruned DFT Spread Filter Bank Multicarrier System for Low PAPR

---

Abstract

Despite being a potential waveform for automation for the fifth genesis, FBMC has notable shortcomings, including high PAPR and cost escalation. Therefore, to develop a waveform contender with high spectral efficiency with low complexity and less peak power ratio, a method has been proposed called Pruned DFT (discrete Fourier Transform) spread along with one tap scaling, we can reduce PAPR. The fashion suggested here has one and the consistent ratio of peak-average power as linearly precoder OFDMA nevertheless uses solo bit transmission per symbol and has much lower out-of-band emigrations. The use of prototype filters is also more stringent than traditional FBMC systems.
