Paper Title: PAPR Reduction by Using DCT and IDCT Techniques

Abstract: In OFDM system, the most important issue is peak to average power ratio. Numerous techniques have suggested to lower Peak to average power ratio. The PAPR of the transmitted signal and its PAPR reduction are proposed in this study using a DCT-based modified selective mapping (SLM) technique. PTS (The partial transmit sequence) methodology was among the earliest and almost successful methods devised. In this paper, n innovative method that uses the IDCT combined with introduction of PTS idea, a better PAPR reduction level was achieved. 64 subcarriers, QAM modulation, different kinds of partitions, and recognised phase angles are used in the result. The evaluations of the proposed method against OFDM, PTS, and IDCT Pre-coded OFDM with PTS was used, A results suggest that this method lower the peak to average power ratio more successfully than all three others. A proposed model can also lower maximum OFDM PAPR level to 7dB.
Keywords: OFDM (ORTHOGONAL Frequency Division Multiplexing), Peak to Average Power Ratio (PAPR), selective mapping (SLM), DCT, IDCT, partial transmit sequence (PTS).
