Non-Orthogonal WDM Systems with Faster than Nyquist Technology

Not Accessible

Your library or personal account may give you access

Abstract

We propose the concept of non-orthogonal WDM and review the principle of FTN. Performance comparison between FTN and constellation shaping is presented. Simulation results of FTN-CS-QAM are shown to support the evolution of 400G WDM.
