摘要

在当今时代，移动通信是人类日常生活中必不可少的一部分，因此调制方案对传输的质量和速度至关重要。正交频分复用(OFDM)是移动通信的最佳方案之一。在本研究中，我们着重于使用OFDM系统的新算法来降低PAPR。为了降低PAPR，本研究提出了部分发射序列(PTS)，并用不同的调制技术进行了仿真。OFDM的主要参数是峰值平均功率比(PAPR)，因为它很高，这对传输系统来说是不理想的。在PTS的低复杂度条件下，该参数已进一步最小化，包括二进制相移键控(BPSK)，正交相移键控(QPSK)和正交调幅(QAM)调制方案。仿真结果表明，在各种调制技术中，BPSK是该算法降低PAPR的最佳技术。

Novel Algorithm to minimize PAPR of OFDM system with Less Intricacy PTS using Various Modulation Schemes

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.
