In optical communications, sphere sha** is used to limit the energy of lightwaves to within
a certain value over a period. This minimizes the energy required to contain information …

We implemented a flexible transmission system operating at adjustable data rate and fixed
bandwidth, baudrate, constellation and overhead using probabilistic sha**. We …

High-symbol-rate coherentoptical transceivers suffer more from the critical responses of
transceiver components at high frequency, especially when applying a higher order …

We propose a novel digital pre-distortion (DPD) based on neural networks for high-baudrate
optical coherent transmitters. We demonstrate experimentally that it outperforms an …

Error correction coding (ie, channel coding) is a key ingredient of any digital
