Modified Square Rooting Companding Technique to Reduced PAPR for FBMC/OQAM

Multicarrier modulation (MCM) have become a fast developing area in wireless communication system. The filter bank multicarrier with offset quadrature amplitude modulation (FBMC/OQAM) system may be the most popular multicarrier modulation technique used for next generation wireless communication technology 5G. It has several advantages such as supporting high data rate, low impulse noise and eliminating inter symbol interference (ISI), inter-carrier interference. However, the main challenging problems of FBMC/OQAM system is the high peak to average power ratio (PAPR). In this paper, we used Square Rooting Companding Technique (SQRT) to reduce the PAPR in the FBMC system, then we modified the SQRT scheme to new scheme which namely by Rooting Companding Technique (RCT). Moreover, new techniques are analyzed with CCDF characteristics and BER Performances. However, the simulation result shows the proposed RCT schemes given significant improvement in the PAPR reduction and increasing BER performance.
