Efficient Frequency Domain Chromatic Dispersion Compensation in a Coherent Polmux QPSK-Receiver
Coherent communications Optical Communications
2015/6/10
We investigate frequency domain chromatic dispersion equalization in an ASIC for digital coherent signal processing. Improved chromatic dispersion tolerance can be achieved by using modified coefficie...
Chromatic Dispersion Compensation by MLSE Equalizer with Diverse Reception
Chromatic Dispersion Compensation MLSE Equalizer Diverse Reception
2015/8/4
We present a concept of improving MLSE by diverse reception. Simulation results show CD tolerance of 42.7G NRZ-OOK system is 382 ps/nm at 3 dB OSNR penalty.
A Novel Field-Detection Maximum-Likelihood Sequence Estimation for Chromatic-Dispersion Compensation
Novel Field-Detection Maximum-Likelihood Sequence Estimation Chromatic-Dispersion Compensation
2015/8/3
We propose a novel field-detection based maximum likelihood sequence estimation (FD-MLSE), and experimentally demonstrate transmission over 372km of field-installed SMF without optical dispersion comp...
