Dalam makalah ini dilakukan simulai kinerja teknik reduksi PAPR dengan skema hybrid enhanced Partial Transit
Sequence (PTS) dan Adaptive Iterative Clipping Filtering (AICF). Skema enhanced PTS bertujuan menaikkan
kandidat sinyal OFDM, yang ikut menaikkan kinerja PAPR. Skema hybrid PTS-AICF memberikan hasil kinerja
yang lebih baik bila dibandingkan dengan teknik enhanced PTS dan skema hybrid enhanced PTS-ICF (Iterative
Clipping Filtering). Simulasi dilakukan dengan mengubah parameter jumlah factor phasa, W = 2 dan 4 pada teknik
PTS dan nilai clipping ratio (CR) = 2 dB dan 6 dB pada teknik clipping-filtering.
