We demonstrate an extended Kalman filtering-enhanced linewidth measurement in short-
delay self-heterodyne interferometry (SDSHI). We found that a modified SDSHI trace closely …

We propose a novel phase recovery scheme designed for coherent space division
multiplexing (SDM) systems with independently-operated asynchronous light sources. The …

In this paper, we propose a novel Gaussian wavelet basis expansion-based phase noise
suppression scheme for polarization-division-multiplexing (PDM) coherent optical …

We propose an improved pilot free phase noise mitigation algorithm for COOFDM systems
using weighted multi-level QPSK partitioning and Kalman filtering. Through extensive Monte …

In this letter, a low-complexity phase noise compensation scheme based on Kalman filtering
theory is experimentally demonstrated for coherent optical orthogonal frequency-division …

In this paper, we propose a novel phase noise suppression method based on Gaussian
basis expansion (GBE) for CO-OFDM systems. We analyze the basic phase noise …

We propose a low‐complexity graph‐based iterative algorithm for the detection of coherent
optical OFDM signals in the presence of residual carrier frequency offset and phase noise …

Spatial division multiplexed (SDM) transmission systems with coherence communication
technology have become an important issue in meeting the demands for the capacity of …

In this paper, for the first time, a novel Lagrange interpolation (LRI) based extended Kalman
filter (EKF) is proposed to compensate inter-carrier interference (ICI) in coherent optical …

In this paper, we developed a phase noise suppression method based on Gaussian wavelet
basis expansion (GWBE) for coherent optical orthogonal frequency-division-multiplexing …
