Perbandingan PAPR Metode CSLM dan SSLM pada Pengirim OFDM

Abstract: OFDM has multiple weaknesses, one of which is a high Peak to Power Average (PAPR). The maximum power value of the OFDM signal will be much greater than the average power, so the efficiency of the amplifier will be reduced. A popular and effective method to reduce PAPR values is by using Conventional Selected Mapping (CSLM). The CSLM method utilizes the PAPR sensitivity to phase rotation by multiplying the signal that will enter IFFT against different phase rotations and then selects the signal with the lowest … Show more

“…In contrast, a Rapp inverse predistorter and a nonlinear power amplifier without a Rapp memory model were applied in the relay transmitter. To reduce the PAPR value of the OFDM signal, a selective mapping (SLM) PAPR reduction technique was used at the transmitter [15]. It aims to reduce the amplitude of the OFDM signal to make the power amplifier operate in the linear region.…”
