Photonic Radio Frequency Orbital Angular Momentum Generation and Beam Steering
Orbital angular momentum (OAM) is a fundamental property of electromagnetic waves and is inherently carried by all frequencies of waves. In particular, OAM applications at radio frequencies (RFs) h…
Performance-Enhanced Three-Dimensional Trellis Coded Modulation Based on Four…
In this paper, an encrypted three-dimensional (3D) trellis-coded modulation (TCM) based on mapping by set-partitioning (MSP) of 3D constellation is proposed, for highly reliable and secure short-re…
Power Sparse Code Division Non-Orthogonal Multiple Access Scheme for Next-Gen…
In this paper, a power sparse code division non-orthogonal multiple access (PSCD-NOMA) scheme is proposed for next-generation flexible optical access, which is based on the multi-stack network. All…
Demonstration of Intelligent Hybrid FSO/RF System Based on Enhanced GRU Predi…
Hybrid free space optical (FSO)/radio frequency (RF) system has emerged as a high-data-rate solution for the last mile access network. In this paper, we establish a hybrid FSO/RF testbed including …
Side-Coupled Fabry-Perot Resonator Filter Based on Dual-Waveguide Bragg Grating
We propose, analyze and demonstrate a side-coupled Fabry-Perot (F-P) resonator filter composed of two dissimilar waveguides with π phase-shifted Bragg grating. The resonance circuit is formed by t…
Supervised Optimal Transport
Optimal transport, a theory for optimal allocation of resources, is widely used in various fields such as astrophysics, machine learning, and imaging science. However, many applications impose elem…
Performance-Enhanced Optical Non-Orthogonal Multiple Access Enabled by Orthog…
In this paper, we propose a novel optical non-orthogonal multiple access (NOMA) scheme based on orthogonal chirp division multiplexing (OCDM) in a low-cost intensity modulation and direct detection…
A Disambiguation Method for Dual-Comb Sampling Frequency Measurement Based on…
A disambiguation method for dual-comb sampling frequency measurement is proposed and experimentally demonstrated. For dual-comb sampling frequency measurement, multiple solutions may exist if only …
Event-Stream Representation for Human Gaits Identification Using Deep Neural …
Dynamic vision sensors (event cameras) have recently been introduced to solve a number of different vision tasks such as object recognition, activities recognition, tracking, etc. Compared with the…
