Abstract

In the 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 to reduce the PAPR using a novel algorithm using the OFDM system. To reduce the PAPR, the Partial transmit sequence (PTS) has been proposed in this study and simulated with different modulation techniques. The main parameter for OFDM is peak-to-average power ratio (PAPR) because it is high which is not desirable for the transmission system. This parameter has been further minimized in low complexity conditions in PTS that include the binary phase-shift keying (BPSK), quadrature phase-shift keying (QPSK), and quadrature amplitude modulation (QAM) modulation scheme. The obtained simulated results show clearly that among various modulation techniques, the BPSK is the optimum technique for proposed algorithm to reduce the PAPR.
