摘要: Peak to Average Power Ratio (PAPR) is defined as the instantaneous power (maximum value) average ratio. PAPR considered be a major problem in OFDM systems. This can cause radical unexpected behavior of signal fluctuation. fluctuation constituted by large number states. The enormous these states leads an additional complexity ADCs and DACs. research addresses previous systems utilizing Turbo Codes. μLaCP technique employed for purpose decreasing PAPR. Moreover, our system was simulated presence AWGN channel with four types codes (without DACs). These were PCCC (typical new), SCCC, Convolutional Our Coded exhibited unchanged BER performance before after use technique. accomplished modifying reduction without sacrificing greatly its attributes.
