An Approach for PAPR Reduction in OFDM System using RCF Technique

Abstract

— OFDM is one of the important modulation techniques for wireless communication which is the advanced version of FDM. Now-a-days congestion networking is growing like AI, IoT, 5G etc. so there is a need of high data rate with low BER. For such a network there is requirement of high-speed secured data transmission that is multicarrier technique OFDM. This modulation technique is useful for current and future scenario. One of the major issue in OFDM is high PAPR and this is happened due to large amount of input data bits. High PAPR results in distortion in bands and power inefficiency using power amplifier. RCF is the technique used in this paper to reduce the PAPR and analyze the results with and without applying PAPR reduction technique. In this paper, after application of 4 clip and filter SNR is improved along with decrement of CCDF of PAPR which is desired.
