Feedforward Carrier Recovery for Coherent Optical Communications (2007, background): “DSP compensation of linear impairments, such as chromatic dispersion (CD) [4]–[6] and polarization-mode dispersion (PMD) [7], [8], is possible.”
Fundamentals of Coherent Optical Fiber Communications (2016, background): “Another important advantage of the digital coherent receiver is the post signal-processing function [33], [34].”
On QoS mechanism profiling in MPLS-TP transport networks (2010, background): “Recently it has been shown that, thanks to digital signal postprocessing, the continuous wave (CW) laser source employed as local oscillator does not need to be phase-locked to the signal, and distortions due to chromatic dispersion and PMD can be compensated [28].”
Evaluation of Sensitivity of the Digital Coherent Receiver (2008, background): “Such a digital coherent receiver also enables various postprocessing functions such as dispersion compensation [7], [8] and wavelength demultiplexing [9].”
Coherent Equalization and POLMUX-RZ-DQPSK for Robust 100-GE Transmission (2008, background): “Coherent detection has recently received attention in the research community because of the potential to recover polarization multiplexed data [7], and correct linear distortions such as CD [8]–[10] and PMD [11], [12].”
Recent advances in coherent optical communication (2009, methodology): “Postcompensation using coherent detection and DSP has been shown to be very effective in chromatic dispersion compensation (CDC) [ 28 ] and intrachannel nonlinearity compensation [37].”
Electronic dispersion compensation by signal predistortion using digital Processing and a dual-drive Mach-Zehnder Modulator (2005, background): “However, the loss of the optical phase information, after direct detection of the intensity modulated signals, limits the amount of group velocity dispersion that can be effectively compensated [7], [8].”
Performance of Dual-Polarization QPSK for Optical Transport Systems (2009, background): “This allows digital linear filters to compensate the linear channel transfer functions [3].”
Digital Equalization of Chromatic Dispersion and Polarization Mode Dispersion (2007, background): “Recent experiments in coherent optical transmission invariably use an oversampling rate of two for CD compensation [12]–[14].”
Fiber Impairment Compensation Using Coherent Detection and Digital Signal Processing (2010, methodology): “FFCR was studied for phase-modulated formats in [35] and [36] and arbitrary constellation in [34].”
