Journal Article 2022 11 08 At present time, mobile communication is essential for the daily life of human beings, and for that, modulation schemes are very important for the quality and speed of transmission. Orthogonal Frequency Division Multiplexing (OFDM) is one of the best schemes for mobile communication. In this study, we focused on reducing the Peak-to-Average Power Ratio (PAPR) using a novel algorithm in the OFDM system. To reduce the PAPR, the modified Low Complexity-Partial Transmit Sequence (LC-PTS) has been proposed in this study and simulated with different modulation techniques. The main parameter for OFDM is PAPR, and reduction of PAPR is desirable for an efficient transmission system. This parameter has been further minimized in LC conditions in Partial Transmit Sequence (PTS) that include the Binary Phase-Shift Keying (BPSK), Quadrature Phase-Shift Keying (QPSK), and Quadrature Amplitude Modulation (QAM) modulation schemes. The obtained simulated results show clearly that among various modulation techniques, BPSK is the optimum technique for the proposed algorithm to reduce the PAPR. https://scientiairanica.sharif.edu/article_24187_b2769ab71109c3634b3115937deaa34a.pdf
