This paper reviews the foundations of the Kramers–Kronig (KK) receiver, a recently
proposed scheme designed to reconstruct a complex-valued signal from the measurement …

We propose a low-complexity digital implementation of the Kramers–Kronig receiver and
analyze its performance and complexity. In simulations and experiments, we find that a …

Digital phase reconstruction of directly detected minimum phase (MP) optical signals using
the Kramers-Kronig (KK) algorithm has recently drawn attention because of its low hardware …

We realize mode-multiplexed full-field reconstruction over six-spatial-and-polarization
modes after 30-km multimode fiber transmission using intensity-only measurements without …

We propose and evaluate a method to estimate the DC bias required for AC-coupled
Kramers-Kronig receivers. The proposed method is based on a spectral analysis of the …

Component characterization is fundamental for understanding the limits of optical devices,
sub-systems, and transmission systems. With the introduction of space division multiplexing …

We investigate the transmission distance of a 20-Gbaud 6-mode dual-polarization QPSK
transmission system using the Kramers–Kronig (KK) receiver based on the mode …

摘要为提高光纤无线电(RoF) 系统的传输性能, 提出了一种基于概率-几何混合整形的圆形**交
振幅调制(PS-GS-Cir-MQAM) 矢量太赫兹信号传输方案. 在Matlab 和VPI …

We demonstrate 1 Tbit/s/λ single-span transmission over a heterogeneous link consisting of
graded-index 50 μm core multi-mode fiber and 6LP few-mode fiber using a Kramers-Kronig …

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 …
