Verification for PAPR Reduction of OFDM Signal Using Partial Transmit Sequences Technique

In this paper, the authors propose an algorithm for PAPR reduction in OFDM systems, based on a Partial Transmit Sequence Technique. In this present work an introduction to multi-carrier modulation emphasizing OFDM (Orthogonal Frequency Division Multiplexing) is given followed by mathematical and qualitative description of OFDM. This paper work presents an overview of the most popular OFDM PAPR-reduction techniques demonstrating that Partial Transmit Sequences (PTS) Technique is a particularly promising reduction technique. It achieves considerable PAPR reduction without distortion, but the high computational complexity of multiple Fourier transforms is a problem in practical systems.
