Abstract :
In this paper, we propose a distorionless PAPR reduction scheme for multicarrier system that´s combining the partial Transmit Sequence (PTS) and the selective mapping (SLM) techniques. Afterwards, we numerically discuss the PAPR characteristics using the complementary cumulative distribution function (CCDF) of the Peak-to-Average-Power-Raito (PAPR). Also, we discuss and compare the computational complexity and the Bit Error Rate (BER) of the proposed scheme with the various schemes. The simulation results show that the combined PTS-SLM scheme (CPS) has a better PAPR and BER performances than (PTS). Besides, (CPS) generates PAPR performance approximately near to the PAPR performance of (SLM).
