Comparison of Single Carrier FTN-QAM and PCS-QAM for Amplifier-less Coherent Communication Systems
Dongdong Zou, Fan Li, Wei Wang +4
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…
Envelope Control Enabled Probabilistic Shaping for Peak Power Constrained IM DD Systems
Dongdong Zou, Wei Wang, Jiawen Yao +7
Probabilistic shaping (PS) has attracted significant attention in intensity-modulation and direct-detection (IM-DD) systems. However, due to the unique system model and inherent co…
Time-varying treatment effect models in stepped-wedge cluster-randomized trials with multiple interventions
Zhe Chen, Wei Wang, Yingying Lu +4
The traditional model specification of stepped-wedge cluster-randomized trials assumes a homogeneous treatment effect across time while adjusting for fixed-time effects. However, w…
Hardware-Efficient and Reliable Coherent DSCM Systems Enabled by Single-Pilot-Tone-Based Polarization Demultiplexing
Wei Wang, Dongdong Zou, Weihao Ni +1
Recently, coherent digital subcarrier multiplexing (DSCM) technology has become an attractive solution for next-generation ultra-high-speed datacenter interconnects (DCIs). To meet…
Simplified Self-homodyne Coherent System Based on Alamouti Coding and Digital Subcarrier Multiplexing
Wei Wang, Dongdong Zou, Zhenpeng Wu +5
Coherent technology inherent with more availabledegrees of freedom is deemed a competitive solution for nextgeneration ultra-high-speed short-reach optical interconnects.However, t…
