Abstract

We propose a novel single-channel Faster-than-Nyquist-DFT-S-OFDM transmitter that allows the sub-bands’ spectra overlap flexibly. By combing duobinary filtering to mitigate inter-sub-band interference, 12% more spectral efficiency is demonstrated in a super-channel experiment over 3360-km transmission.
