Comparative Analysis of OFDM Systems based on PAPR Reduction for Cyclic Shifted Partial Transmit Sequence and Conventional Partial Transmit Sequence for Different Shift Values Using different Modulation Schemes

Harshita Soni, Gaurav Gupta

High PAPR is one of the serious issues in OFDM Systems which affects the orthogonality of OFDM systems. This paper demonstrates the use of shift value sets in cyclically shifting the OFDM transmit sequence, which leads to generation of alternative transmit sequence by using cyclic shifts rather than phase rotations which forms the basis of conventional Partial Transmit Scheme. The two approaches are tested for QPSK and BPSK modulation. It is found that Cyclic Shifted Partial transmit scheme out performs the conventional Partial transmit Sequence in reducing the PAPR for both the modulations.
