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…
