Comparison of Single Carrier FTN-QAM and PCS-QAM for Amplifier-less Coherent Communication Systems
arXiv:2601.17803
Abstract
A performance comparison of FTN-QAM and PCS-QAM for amplifier-less short-reach coherent communication systems is provided. With the applications of phase tracking partial response DFE and turbo equalization strategy, FTN-16QAM exhibits about 0.9dB power margin advantage over PCS-64QAM.
