Peak-to-Average Power Ratio (PAPR) is the major drawback in Orthogonal Frequency Division Multiplexing (OFDM) systems, which may result in signal distortion, loss of orthogonality in OFDM signals etc. Hence, it is the most concerned problem in OFDM systems, which has to be reduced. Of all the available PAPR reduction techniques, Partial Transmit Sequence (PTS) scheme is the most efficient and attractive one. But, the original PTS scheme requires large computations in order to transmit the optimum signal with low PAPR from all available combinations of candidate signals. This paper proposes a new efficient PTS scheme which utilizes the correlation property among all available candidate signals to reduce the computational complexity.
