Kramers-Kronig Receiver Combined With Digital Resolution Enhancer
arXiv:2107.10626 · doi:10.1364/OFC.2021.Th4D.4
Abstract
A Kramers-Kronig receiver with a continuous wave tone added digitally at the transmitter is combined with a digital resolution enhancer to limit the increase in transmitter quantization noise. Performance increase is demonstrated, as well as the ability to reduce the number of bits in the digital-to-analog converter.
