PAPR reduction in FOFDM system using Group Codeword Shifting technique

Filtered Orthogonal Frequency Division Multiplexing (FOFDM) system is one of 5G multicarrier waveform that provide high data rate and capable improve spectral efficiency. The main disadvantage for FOFDM is high peak to average power ratio (PAPR) that faced by every multicarrier modulation technique. This paper we investigate used of a Group Codeword Shifting (GCS) method for peak to average power ratio (PAPR) reduction in FOFDM system. Beside that we also comparing result of peak to average power ratio (PAPR) reduction with low complexity in FOFDM used a Group Codeword Shifting (GCS) method with Median Codeword Shift (MCS), Selective Codeword Shift (SCS) method and Conventional FOFDM. The simulation result show that the Group Codeword Shifting (GCS) method is 45.5 % reduction compare with Conventional FOFDM, while 21.8% better than Median Codeword Shift (MCS) and 19.1% better than Selective Codeword Shift (SCS) method for peak PAPR reduction
