Analysis of PAPR Reduction using Partial Transmit Sequence (PTS) Technique in OFDM

Abstract: From a current scenario demand of high speed multimedia data services increase day by day. Orthogonal Frequency Division Multiplexing (OFDM) is one of the important multi carrier systems and it is famous because it allow large no of subcarriers, high speed data rate and universal coverage with high speed mobility. OFDM is considerably degrades by peak-to-average-power ratio (PAPR).There are many scheme are developed to reduce the PAPR in OFDM system. In this paper we use Partial Transmit Sequence (PTS)technique to decrease the PAPR and simulation data of this technique is done by using Matlab.
