Proceedings ArticleDOI
Computationally efficient hardware design of RF-pilot tone based phase noise compensation for optical OFDM
TL;DR: This work investigates the optimum design parameters of a bit-true computationally-efficient RF-Pilot-tone implementation and finds that for a 23.9-Gb/s receiver an implementation penalty is observed using only 27% of Virtex5 resources.
Proceedings ArticleDOI
Accurate Estimation of Transmitter I/Q Skew for High-Rate Spectrally Efficient Optical Transponders
TL;DR: A phase noise canceler is presented to improve the accuracy of transmitter I/Q skew estimation for high baud-rate optical transponders using high-order modulation formats to reduce the probability of failure due to estimation errors.
Proceedings ArticleDOI

TL;DR: A novel strategy to reduce the computational complexity of the back-propagation method with negligible system performance degradation considering different fiber types is analyzed.
Proceedings ArticleDOI
Impact of PMD and nonlinear phase noise on the global optimization of DPSK and DQPSK systems
TL;DR: Using a global optimization algorithm, this work maximizes the reach of DPSK and DQPSK systems including PMD and nonlinear phase noise at data rates ranging from 5 Gbit/s to 230 Gbits/s.
Journal ArticleDOI
Performance of Stereo Multiplexing in Single Channel and DWDM Systems Using Direct Detection with Optimum Dispersion Maps
TL;DR: It is shown that the best performance and robustness is obtained by sharing the information between two carriers, and that Stereo is only 1dB below dual-carrier NRZ-DQPSK.
