  Abstract

OFDM(orthogonal frequency division multiplexing) is very effective forhigh data rate transmission system. However, communication performance becomes worse because of nonlinear distortion resulting from the PAPR. In this paper, we like to propose a tone-controlled CI/OFDM system including the IMD (inter-modulation distortion) reduction method in order to improve the BER performance. In this tone-controlled CI/OFDM system, control tone is additionally inserted in each data symbol of CI/OFDM system to make the CI/OFDM lower the PAPR and robust to nonlinear distortion. So, tone-controlled CI/OFDM using the IMD reduction method shows better BER (bit error rate) performance than methods based on PAPR reduction.
