However, it faces several atmospheric turbulence challenges that can adversely affect its performance, including weather-induced attenuation, polarization-induced fading, polarization mismatches, and spectral efficiency loss. This paper presents the Resilient Adaptive Polarized Optical Transmission (RAPOT) framework, which integrates Adaptive M-ary Differential Quadrature Phase-Shift Keying (AM-DQPSK), Spatial Polarization Multiplexing (SPM), Dynamic Spatial Mode Switching (DSMS), and Polarization-Time Coding (PTC) to enhance modulation, multiplexing, and overall system resilience. AM-DQPSK allows the system to dynamically adjust modulation order based on real-time channel conditions, mitigating the impact of weather-induced attenuation and maintaining reliable communication. SPM increases spectral efficiency by utilizing orthogonally polarized carriers, while also providing polarization diversity to reduce the effects of polarization-induced fading. DSMS enhances robustness by adapting spatial modes to real-time environmental changes, effectively countering polarization mismatches. Finally, PTC encodes data across polarization and time domains, overcoming spectral efficiency loss and providing redundancy for signal recovery in challenging environments. The performance of the RAPOT system is evaluated through extensive experimental simulations and the simulation results for RAPOT system operating at 20 Gbps indicate substantial performance improvements under moderate turbulence conditions. The system achieved a Bit Error Rate (BER) of 10⁻⁵ at Signal to Noise Ratio (SNR) 25, demonstrating robust error performance. The outage probability (OP) is minimized to 0.03, while the link range extended to 2.8 km, showcasing the system's capability to maintain reliable communication even in challenging environments. Additionally, the RAPOT system demonstrated a 25 % increase in spectral efficiency, reaching 8 bits/Hz, compared to conventional systems. These results highlight the RAPOT system's effectiveness in mitigating the challenges posed by atmospheric turbulence and ensuring high-speed FSO communication.</div></div>","PeriodicalId":19513,"journal":{"name":"Optik","volume":"326 ","pages":"Article 172262"},"PeriodicalIF":3.1,"publicationDate":"2025-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143480584","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
