Novel Repeating Clipping and Filter with Partial Transmit Sequence Technique for Reducing PAPR in FBMC/OQAM System

摘要

In this paper, a novel approach which merges two recognized signal processing techniques with repeating clipping filtering (RCF) and conventional partial transmit sequence (PTS) techniques has been proposed and analyzed. The key objective is to damp and set the ratio between peak and average powers of the filter bank multicarrier (FBMC) recently used in the 5G mobile systems. The hybrid proposed peak-to-average power ratio (PAPR) scheme is referred to as RCF-PTS technique. Simulation results show that our proposed PAPR reduction technique achieves better power reduction factor compared the clipping and filter (CF) scheme (around 4 dB) and to the PTS technique (around 3 dB).
