Paper Reduction in Form Systems Using Slm and Pts Schemes

Abstract

Orthogonal frequency division multiplexing (OFDM) is a multi carrier modulation technique where the  revolution of 4G wireless communication is focused towards OFDM systems. The major drawback of OFDM system is high Peak to average power ratio .The proposed work is based on peak to average power ratio (PAPR) reduction by the  implementation of  Selective Mapping Technique (SLM) and Partial Transmit Sequence (PTS) methods. Here PAPR reduction efficiency parameter which will be applied on the complementary cumulative distribution function (CCDF) of each technique to compare the results. Using the proposed efficiency formula, we show that PTS system performance improves when increasing the probability, whereas the SLM system performance gets impaired when increasing the probability within the same range. Simulation results show that the complexity is reduced by using newly proposed algorithm than normal schemes.
