PAPR Reduction of SC-FDMA Signals Using Optimized Additive Pre-distortion

One challenge of employing high-order modulations in single carrier frequency division multiple access (SC-FDMA) systems is the resultant high peak-to-average power ratio (PAPR). We propose a novel PAPR reduction scheme by jointly considering the PAPR reduction and the incurred bit error rate (BER) degradation for SC-FDMA systems with high-order modulations… CONTINUE READING
