摘要：

The most importantdisadvantage of Orthogonal Frequency Division Multiplexing (OFDM) is high Peak-to-Average Power Ratio (PAPR). Designing High Power Amplifiers (HPA) with high peaksis very difficult in manufacturing which becomes costlier and complex. VoluminousPAPR reduction techniques have been proposed in which the present technique is Partial Transmit Sequences (PTS) with finest PAPR reduction. In this paper the evaluationof OFDM system, Precoded PTS OFDM system with assorted precoding methods like Discrete Fourier Transform (DFT) Precoded PTS OFDM, Discrete Hartley Transform (DHT) Precoded PTS OFDM, and Walsh-Hadamard Transform (WHT) Precoded PTS OFDM for M-QAM is scrutinized for enhanced PAPR reduction.
