Also, this technology leverages the intelligent software innovations to deliver high quality and smooth video recording experiences. Despite advancement in machine learning (ML) algorithms for video stabilization, there are numerous challenges, especially when applying 5G technologies like stable and unstable videos for training performance. Consequently, video stabilization includes complex analyses such as frame interpolation and motion assessment. Moreover, the advanced stabilization modes are developed to analyze the motion data. Nevertheless, they decrease or fail to calculate the features and provide poor results. To overcome these issues, an adaptive video stabilization methodology is proposed. In the proposed method, a novel Convolution Neural with StabNet based Hawks Optimization (CNSbHO) algorithm is introduced. In this research, hand-held video clips generally suffer from unwanted video jitters due to unbalanced camera motion. Therefore, 5G ultra-low latency with respect to drone footage video feeds is taken as the stabilization process. Then, a pre-processing Gaussian filter was enabled to enhance consistency and quality. Hereafter, a Convolution Neural Network (CNN) was used to extract the features, and motion estimation is also done in this section with feature tracking point of CNN. Furthermore, end-to-end stabilization strategy as StabNet model can provide stabilized frame outputs. Then, the Harris Hawks Optimization (HHO) algorithm was used to enhance the accuracy of the entire performance. The developed CNSbHO strategy was implemented in Python and validated using the 5G traffic datasets. In order to validate the effectiveness of the developed strategy, we selected the traditional algorithms for the comparison in terms of learned perceptual image patch similarity (LPIPS), structural similarity index (SSIM), accuracy, and peak signal-to-noise ratio (PSNR). The comparative assessment confirms that the proposed method outperforms conventional stabilization techniques, making it a reliable solution for real-time video processing tasks.</p>\u0000 </div>","PeriodicalId":100725,"journal":{"name":"Internet Technology Letters","volume":"8 5","pages":""},"PeriodicalIF":0.9,"publicationDate":"2025-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144705704","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, RF impairments, such as thermal noise, phase noise, and nonlinearity losses, severely hinder multiple-input multiple-output (MIMO) communication systems. These deficiencies restrict performance in high-frequency 6G settings due to signal distortion, phase instability, and a poor signal-to-noise ratio (SNR). An Adaptive RF Compensation and Distortion Mitigation Framework (ARC-DMF) is proposed here to resolve these issues. Dynamic compensation for the distortions inflicted by radio frequency interference is accomplished through the framework's adaptive filtering and machine learning-based correction system, ensuring good signal transmission and enhanced data integrity. The ARC-DMF approach employs digital pre-distortion (DPD) techniques, deep learning-based compensation modeling, and real-time distortion estimation to minimize the effects of nonlinear distortion effects, phase noise variations, and thermal noise fluctuations. Bit error rate (BER), capacity enhancement, error vector magnitude (EVM), and spectral efficiency are some of the important performance metrics tested in several 6G operational scenarios through substantial simulations. The simulation findings show that ARC-DMF substantially improves the performance of MIMO communication over traditional compensation methods, with reduced BER, better resilience to phase noise, and more resilient transmission. Enabling efficient and reliable wireless communication in high-frequency RF situations, this study's findings offer insights into RF impairment mitigation for next-generation 6G MIMO systems.</p>\u0000 </div>","PeriodicalId":100725,"journal":{"name":"Internet Technology Letters","volume":"8 5","pages":""},"PeriodicalIF":0.9,"publicationDate":"2025-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144657639","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
