• This paper deals with the Peak to Average Power Ratio (PAPR) drawback appeared in Filter-Bank Multi-Carriers with Offset-QAM (FBMC-OQAM) which is the candidate waveform in 5G wireless communication systems. A post-Inverse Discrete Fourier Transform (IDFT) Discrete Sliding Norm Transform (DSNT) is proposed based on L 2 -metric and the norm of five samples at each sliding operation. The overlapping structure of FBMC-OQAM is considered in the proposed L 2 -by-5 DSNT formulation. It can significantly reduce the PAPR in FBMC-OQAM systems, which ensures a linear amplification at the High Power Amplifier (HPA) and avoids signal distortion. The main advantages of this technique are its lower computational complexity compared to the known techniques, and the fact that it does not require any Side Information (SI) at the receiver. Simulation results show that the L 2 -by-5 DSNT technique can achieve an improvement of 40% in PAPR reduction at CCDF = 10 −3 compared to the original FBMC-OQAM system.
