Direct Detection Under Tukey Signalling
arXiv:2105.12802 · doi:10.1109/JLT.2021.3109852
Abstract
A new direct-detection-compatible signalling scheme is proposed for fiber-optic communication over short distances. Controlled inter-symbol interference is exploited to extract phase information, thereby achieving spectral efficiencies about one bit less, per second per hertz, of those of a coherent detector.
