Peak to average power ratio reduction of orthogonal frequency division multiplexing system with a significant low complexity

Research output: Contribution to journalArticle

Abstract

The Orthogonal Frequency Division Multiplexing (OFDM) has been widely used in many applications in the last decade. It provides good benefits compared to the single carrier systems. However, it has a bad property represented by the high-output Peak to Average Power Ratio (PAPR) which is considered as its major problem. There are many techniques to reduce the PAPR values such as the best one called Selected Mapping (SLM) method. In this study, a novel technique has been used to reduce the PAPR and it depends on a cascade of Inverse Fast Fourier Transform (IFFT). The analysis proved that the computational complexity has been reduced significantly and the simulation results showed that the PAPR reduced also without affecting the Bit Error Rate (BER).
