Abstract:
An optical signal transmission can use probabilistically shaped technique to improve performance and increase the transmission capacity. For instance, a 30-Gbit/s/λ, probabilistically shaped (PS) 1024-QAM DFT-S OFDM was experimentally demonstrated over 40-km SSMF in an intensity modulation-direct detection system. The Achievable Information Rate (AIR) 9.5344-bits/QAM symbol of PS-1024-QAM modulation is first achieved in the experiment and shows feasibility for OFDM.

Claim (Index 5):
The method of  claim 1 , wherein the OFDM signal is a Discrete Fourier Transform-Spread (DFT-S) OFDM signal, and wherein the generating of the OFDM signal from the parallel complex symbols includes:\n performing an L-point Fast Fourier Transform (FFT) on the parallel complex symbols to obtain an L-point DFT-S signal; and performing an N-point Inverse Fast Fourier Transform (IFFT) on the L-point DFT-S signal to obtain the DFT-S OFDM signal, wherein N is equals to a number of subcarriers of the DFT-S OFDM signal and wherein N and L are integers.
