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 18):
A wireless communication device comprising a processor and a memory, wherein the memory stores instructions that, when executed, cause the processor to:\n receive and converting a real-value OFDM signal to a complex-value OFDM signal; remove cyclic prefix from the complex-value OFDM signal; convert, after removing the cyclic prefix, the complex-value OFDM signal from serial data to parallel data to obtain a parallel OFDM signal; generate, from the parallel OFDM signal, complex symbols based on a probabilistic shaped quadrature amplitude modulation (PS-QAM) scheme; and de-map the complex symbols using a probabilistic shaped quadrature amplitude demodulation scheme to obtain an output signal.
