Performance Investigation of DFT-Spread OFDM Signal for Short Reach Communication Systems Beyond NG-PON2EI

摘要

In this paper, we investigate the performance of a discrete Fourier transform (DFT)-spread OFDM signal in an intensity-modulation/direct-detection system. We find that DFT-spread OFDM could reduce the peak-to-average power ratio effectively and hence improve the nonlinearity tolerance. Furthermore, DFT-spread OFDM also improves the receiver sensitivity performance and shows good robustness to nonlinearity distortion caused by low-bit resolution digital-to-analog converters and analog-to-digital converters. The measured bit error ratio...更多
