Abstract :
We study the impact of tight optical filtering on the performance of 28 GBaud Nyquist WDM PDM-8QAM. Performance degradation and its mitigation using maximum-a-posteriori (MAP) detection are investigated. System sensitivity to laser frequency detuning, and Gaussianity of statistics are studied as well.
