Partial Transmission Sequence (PTS) method proposed is one of the methods to reduce
the Peak to Average Power Ratio (PAPR) of Orthogonal Frequency Division Multiplexing
(OFDM) system. In which each symbol of OFDM in the frequency domain is divided into sub
blocks and each one, multiplied by a phase factor to rearrange the origin symbol to a version
with the lowest PAPR. This method is based on changing the phase of each sub blocks to
reduce the probability of occurrence high PAPR. The nonlinear behavior of the phase affect's
the accuracy of reduction which makes it different as compared with this method.
In this paper, a proposed method is suggested to reduce the complexity of such method
