In recent days, Orthogonal Frequency Division Multiplexing technique plays an important position in wireless digital communication system. OFDM technique is a Multicarrier Modulation method in which high capacity data is transmitted over a single communication channel. The biggest problem in this technique is that it results in high Peak �to- Average Power Ratio (PAPR), due to the usage of several sub carriers for modulation. A Large PAPR distorts the transmitted signal, if the transmitter keeps nonlinear circuit components, which in turn increases the system complexity and reduces the efficiency. Several methods are deployed to condense the PAPR level and System complexity. To improve PAPR performance, a novel method called Partial Transmit Sequence (PTS), which is a distortion less technique, can be used. But when implementing PTS algorithms in OFDM systems, several iterations of IFFT operations are done, which increases computational complexity. A new algorithm to reduce the computational complexity in PTS based PAPR reduction methods in OFDM transmitters are discussed in this paper.
