We present an automatic compensator that effectively mitigates signal distortion due to
polarization-mode dispersion (PMD). Accurate compensation is achieved by utilizing a …

A nonlinearity-tolerant constant composition distribution matching (CCDM) scheme based
on a parallel bisection architecture is proposed. Compared with CCDM based on arithmetic …

This article proposes a new estimation and compensation approach to mitigate several
linear and widely linear effects in coherent optical systems using digital signal processing …

Starting from the maximum likelihood criterion, we derive a novel blind chromatic dispersion
(CD) estimation method in the presence of unknown data, propagation delay, polarization …

This thesis investigates algorithms and subsystems for digital coherent optical networks to
alleviate system requirements and enable spectrally efficient systems. Spectral shaping of …

This paper reports the DSP-based prototype compensator we have made to compensate the
polarization mode dispersion (PMD) in fibers. It was tested in one channel of a 40× 43-Gb/s …

Dual polarization quadrature phase shift keying (DP-QPSK) is currently the main modulation
format for high-speed optical fiber communications, and its simulation modeling has …

One of the most severe impairments that affect coherent optical systems employing high-
order modulation formats is phase noise due to transmit and receive lasers. This is …

Publisher Summary This chapter is a comprehensive and in-depth treatment of self-coherent
transmission systems, including theoretical considerations, receiver technologies …

In this paper we review several digital signal processing (DSP) algorithms recently proposed
(or introduced) for coherent optical communication system. There include the digital …
