Abstract

An orthogonal frequency division multiplexing (OFDM) system has a number of orthogonally modulated subcarriers, which can give a large peak-to average power (PAPR). The PAPR reduces the efficiency of RF power amplifier in OFDM systems. In this paper, we propose a new PAPR reduction method, which pre-scrambles data sequence for high speed data processing in OFDM. The proposed method uses a correlator for the reduction of PAPR value and calculations. We have compared the new method with a partial transmit sequences (PTS) method. As a result, the new method has shown that it permits a considerable improvement in the computational complexity with achieving a reasonable PAPR reduction.
