OFDM is a high data rate modulation technique used in the downlink of 4G system. Due to the difficulty of PAPR, usage of OFDM system affects the battery period of mobile terminal. So that new accessing technique called SCFDMA system which is employed in the uplink system. But still the PAPR problem persists in SCFDMA system which has to be overcome. A statistical method, Partial Transmit Sequence can be used with SCFDMA to reduce the PAPR even more. In this paper, the PAPR in SCFDMA system is
