Performance Analysis of PAPR Reduction in FBMC-OQAM Using DCT with Mu-companding in 5G System

P. Maniganda and Dr.T. Kavitha

FBMC-OQAM, abbreviated as Filter Bank Multi Carrier along with Offset Quadrature Amplitude Modulation is a multi-carrier scheme is aiding in the development of the fifth generation (5G) wireless systems for long distance communication. FBMC-OQAM system provides high bandwidth efficiency and high transmission rate. However, the transmitted signal causes severe Peak to Average Power Ratio (PAPR) leading to severe performance degradation of the system. Because of the signal overlapping structure of FBMC-OQAM, most of the conventional PAPR reduction methods cannot work well for the 5G. In this paper, we propose a hybrid PAPR reduction scheme based on Discrete Cosine Transform (DCT) with Mu-law companding method for 5G FBMC-OQAM system. Output simulation results inferred that our proposed scheme can considerably reducing PAPR in FBMC-OQAM system which is a performance improvement not only PAPR and also Bit Error Rate (BER) compared to conventional methods like clipping, PTS, SLM and companding techniques.
