Peak to average power ratio reduction in spectrally efficient FDM using repeated clipping and filtering

Multi-carrier transmission may be considered one of the important developments in wireless communications. Spectrally efficient frequency division multiplexing (SEFDM) is a promising multi-carrier modulation which can significantly improve utilization spectral. The SEFDM has high peak to average power ratio (PAPR) like any multicarrier system. High PAPR reduces random forest (RF) transmitter amplifier efficiency, minimize use this technique limited supply transmitters. In work, repeated clipping and filtering method introduced reduce with minimum or no out band radiation. results simulated approach show that was reduced from 16.264 dB 7.9146 marginal degradation system performance when varied 4 2.
