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.
