Modified PTS with Interleaving for PAPR Reduction of OFDM Signal with QPSK Subblocks

Pandurangan Mukunthan and Perumal Dananjayan
 Abstract—Orthogonal Frequency-Division Multiplexing (OFDM) is a striking technique for achieving high-bit-rate wireless data transmission as it has the ability to cope with severe channel conditions. However, the potentially large Peak-To-Average Power Ratio (PAPR) has limited its application. Partial Transmit Sequence (PTS) is an attractive scheme for PAPR reduction without distortion, but to obtain preferable PAPR performance it needs many Inverse Fast Fourier Transforms (IFFTs) which results in high complexity. In this paper, a modified PTS scheme combined with interleaving for PAPR reduction using Quadrature Phase Shift Keying Modulation (QPSK) has been presented. The scheme is very efficient and avoids the use of any extra IFFTs as was done in PAPR reduction by ordinary PTS technique. The simulation result shows that PAPR performance is improved with the increase in number of subblocks.

Index Terms—OFDM, PAPR, interleaving, subblock partition scheme.
