3D Printed Multi-Beam OAM Antenna Based On Quasi-Optical Beamforming Network
In this paper, a multi-beam orbital angular momentum (OAM) antenna is proposed. By employing 3D printed millimeter-wave quasi-optical beamforming network (BFN), the emitted OAM wave can realize pas…
A Coalesce Security System of PDM and SDM Based on a Flexible Configuration o…
The purpose of this study is to present a security system that combines PDM and SDM and is based on the flexible configuration of multi-channel keys. The proposed system will utilize three distinct…
Fine-Grained Image Analysis With Deep Learning: A Survey
Fine-grained image analysis (FGIA) is a longstanding and fundamental problem in computer vision and pattern recognition, and underpins a diverse set of real-world applications. The task of FGIA tar…
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…
Distilling Knowledge by Mimicking Features
Knowledge distillation (KD) is a popular method to train efficient networks (“student”) with the help of high-capacity networks (“teacher”). Traditional methods use the teacher’s soft log…
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…
Secure OCDM Mode Division Multiplexed Short-Reach Optical Communication Based…
A secure orthogonal chirp division multiplexing (OCDM) mode division multiplexed (MDM) short-reach optical communication based on time-frequency joint perturbation is proposed in this paper. Firstl…
Practical Kramers-Kronig Phase Retrieval FIR Filter With the Gibbs Phenomenon
Kramers-Kronig (KK) receiver shows strong feasibility since the phase can be extracted from the detected intensity through the Hilbert transform (HT). To reduce the complexity and make the HT more …
Chaotic Power Division Multiplexing for Secure Optical Multiple Access
This paper proposes a novel chaotic power division multiplexing (CPDM) for secure optical multiple access. The proposed CPDM can not only improve spectral efficiency and the user number by multiple…
