We propose a DSP-free coherent-lite system that requires neither high-speed DSP nor high-
resolution signal converters for deployment inside datacenters over single mode fiber links …

The physical layer security of radio-over-fiber (RoF) system is a very important problem for
future communication. In this paper, a novel probabilistic shaping (PS) based constellation …

In this article, we propose a high-security transmission scheme of power division 3-D carrier-
less amplitude and phase (PD-3D-CAP) based on polling-permutation encryption and noise …

Channel independent precoding technique has been widely used in optical discrete multi-
tone (DMT) transmission systems to compensate unbalanced impairments induced by …

Disaggregated rack-scale data centers have been proposed as the only promising avenue
to break the barrier of the fixed CPU-to-memory proportionality caused by main-tray direct …

The intra-and inter-data center links face continuously increasing pressure on the
transmission capacity while having to meet strict constraints in cost and power consumption …

In intensity-modulation and direct-detection (IM-DD) communication systems, electrical
chromatic dispersion (CD) compensation cannot be directly applied in the transceivers due …

In this paper, a channel response dependent noise shaping (CRD-NS) technique is
proposed and experimentally demonstrated for the pre-equalized discrete multi-tone (DMT) …

Advanced nonlinear digital signal processing technologies, which bring significant
performance gain for high-speed optical interconnects, are highly constrained by huge …

A novel, probabilistically shaped star-CAP-16/32 modulation based on constellation design
with honeycomb-like decision regions is proposed in this paper. The proper geometric …
