Optimum Signal Constellation Design for Rotationally Symmetric Optical Channel with Coherent Detection
Modulation Coherent communications Optical channel capacity Rotationally symmetric optical channel
2011/5/21
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...
