Abstract :
One of the main limitations for OFDM-based transmission systems is the high Peak-to-Average Power Ratio (PAPR) of the transmitted signals. In this paper, the residue number system (RNS) based OFDM transmission scheme is proposed to reduce the PAPR, which uses the features of RNS to control the dynamic range of the transmitted signals and avoid the nonlinear distortion for the PAPR reduction. Experimental results show that at least 5dB of PAPR performance is improved with the proposed method, compared with the original OFDM.
