A Review On Precoding-Based Papr Reduction Technique For Uf-Ofdm And Filtered-Ofdm Modulations In 5g Systems
Mohit Choubey,  Dr. Anubhuti Khare
5G networks employ multicarrier modulations (MCM)s such as filtered-orthogonal frequency division multiplexing (F-OFDM) and universal filtered orthogonal frequency division multiplexing (UF-OFDM) as a solution to overcome the challenges of high data rates and spectral efficiency. However, MCMs have high peak to average power ratio (PAPR) which drives the power amplifier (PA) in the linear region resulting in the reduced efficiency. To overcome this problem PAPR should be reduced.
Keywords- 5G, UF-OFDM, F-OFDM, peak to average power ratio (PAPR), IAPR, precoding, Zadoff-Chu Transform (ZCT), Power Spectral Density (PSD), BER.
