Advanced Photonics Research, Volume 7, Issue 3, March 2026.This article proposes a deep learning (DL) approach for modeling and optimizing frequency‐doubled radio‐over‐fiber links. By collectively replacing traditional components with DL model, accurate system evaluation is achieved. Moreover, through an end‐to‐end architecture, performance optimization is accomplished.

Dynamic QAM Mapping for Physical-Layer Security Using Digital Chaos
IEEE Access, 2018 This paper proposes and experimentally demonstrates a physical-layer data encryption scheme using multi-fold chaotic mapping of quadrature amplitude modulation (QAM) symbols in orthogonal frequency-division-multiplexed passive optical network (OFDM-PON).

Physical Layer Network Coding for Two-Way Relaying with QAM
, 2013 The design of modulation schemes for the physical layer network-coded two way relaying scenario was studied in [1], [3], [4] and [5]. In [7] it was shown that every network coding map that satisfies the exclusive law is representable by a Latin Square ...

Advanced Science, Volume 13, Issue 16, 18 March 2026.Radiotherapy induces tumor cells to release microparticles (RT‐MPs) into the circulation. The mitochondrial DNA carried by these RT‐MPs activates the STING/NLRP3/GSDMD axis in splenic neutrophils, triggering IL‐1β secretion. This, in turn, enhances dendritic cell function and facilitates the formation of cytotoxic T lymphocytes, thereby promoting ...

Low Complexity Golden Code Analytical and Deep Learning-Based Sphere-Decoders for High-Density M-QAM
IEEE Access, 2022 In this paper, we develop low complexity Golden code sphere-decoding (SD) algorithms for high-density M-ary quadrature amplitude modulation (M-QAM). We define the high-density M-QAM as having modulation orders ( $M$ ) of at least 64, i.e.

On Performance of Hexagonal, Cross, and Rectangular QAM for Multi-Relay Systems
IEEE Access, 2019 Error performance is considered as one of the most important performance measures, and deriving the closed-form expressions for efficient modulation techniques over generalized fading channels is important for future cellular systems.

Super‐Robust Telecommunications Enabled by Topological Half‐Supermodes
Advanced Science, Volume 13, Issue 13, 3 March 2026.Through topological half‐supermode engineering, we realize a valley‐ridge gap waveguide that is directly compatible with conventional waveguides and features topological protection. This design halves the lateral size via a PEC boundary, enabling direct TE₁₀‐mode matching and robust bend‐immune transmission.
