In this paper, we improve the pseudo pilot-aided orthogonal basis expansion based (PS-
OBE) phase noise suppression method proposed in our recent work by linearly interpolation …

We proposed and demonstrated an in-band optical signal-to-noise ratio (OSNR) monitoring
method for a polarization-division-multiplexed coherent optical orthogonal frequency …

Receiver in-phase/quadrature (IQ) mismatch is hard to mitigate at the receiver via using
conventional method in polarization division multiplexed (PDM) coherent optical orthogonal …

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 …

Phase noise effects must be taken into account when studying the performance of coherent
optical orthogonal frequency division multiplexing (CO-OFDM) transmission systems. One …

Orthogonal chirp-division multiplexing (OCDM) was recently proposed as a promising
modulation technique for high-speed fiber-optic communications due to its resilience to …

The vulnerable sensitivity to laser linewidth induced inter-carrier interference (ICI) has long
been recognized as a major problem to coherent optical orthogonal frequency-division …

A unified framework for phase noise suppression is proposed in this paper, which could be
applied in any coherent optical block transmission systems, including coherent optical …

In this paper, we investigate and characterize a new approach of adopting best-fit bounding
box method for common phase error estimation in coherent optical OFDM systems. The …
