Abstract

The high Peak to Average Power Ratio (PAPR) of the transmitted signals the main drawback of OFDM
system. OFDM Suffers as the no of Subcarriers operating in the large dynamic range operates in the non-linear region
of amplifier due to OFDM suffer the PAPR problem Application of high power amplifiers results in increased
component cost. To reduce Peak -to-average power ratio (PAPR) in orthogonal frequency division multiplexing (OFDM)
Partial transmit sequence scheme is a promising algorithm. Partial Transmit Sequence (PTS) consist of several inverse
fast Fourier transform (IFFT) operations and complicated calculations to obtain optimum phase sequence which results
in increasing the computational complexity of PTS. There are various methods and scheme has been proposed to reduce
the complexity of the algorithm with no increment or reduction in the PAPR also. This article presents a review of
various complexity reduction techniques for PTS.
