Optimum Signal Constellation Design for Rotationally Symmetric Optical Channel with Coherent Detection
Modulation Coherent communications Optical channel capacity Rotationally symmetric optical channel
2015/5/21
We present an optimum signal-constellation design (OSCD) method to obtain the optimum probabilities and mass points by split-step method. The OSCD increases channel capacity by 1.02bits/channel use af...
Optical Performance Monitoring of Data Degradation by Evaluating the Deformation of an Asynchronously Generated I/Q Data Constellation
Optical Performance Monitoring Degradation Asynchronously Generated I/Q Data Constellation
2015/7/17
We present a technique of using asynchronously generated constellation pattern to simultaneously monitor CD and first order PMD in DQPSK systems. By characterizing deformations in the patterns, the am...

The May 31 transfer of Launch Pad 39B at NASA's Kennedy Space Center in Florida from the Space Shuttle Program to the Constellation Program is the next step in preparing the first flight test of the a...
Fiber Nonlinearity Mitigation by PAPR Reduction in Coherent Optical OFDM Systems via Active Constellation Extension
Fiber Nonlinearity PAPR Optical OFDM Systems Active Constellation Extension
2015/8/4
We consider Active Constellation Extension to reduce the PAPR in CO-OFDM systems. We find that the nonlinearity threshold is improved by 1.5 dB at a reach of 400 km SSMF fiber.
