In this context, one technique that has garnered significant attention is visible light communication (VLC) due to its ultra-wide and license-free frequency resource. However, a critical issue in utilizing VLC in IoT lies in its lack of smooth cooperation with ubiquitous radio frequency (RF)-based wireless networks. RF signals can use duplex techniques to transmit and receive bidirectional signals with one antenna. In contrast, VLC's light-emitting diodes (LEDs) and PIN diodes cannot operate in duplex mode, posing challenges in establishing two unidirectional VLC links. To address the mismatch between VLC and RF, we propose a light-based RF transceiver design called LiRF, capable of smooth transmission of RF signals through VLC for IoT devices. To verify its feasibility, we first build a prototype using 802.11ax (WiFi-6) network interface cards (NICs) in the 5 GHz channel. Experimental results show that LiRF is compatible with the 802.11bb standard, supporting TCP/IP data streams at 750 Mbps with a 200 MHz Superluminescent Diode-PIN (SLD-PIN) transceiver and at 600 Mbps with a 180 MHz LED-PIN transceiver. To the best of our knowledge, this is the first real-time bidirectional VLC system utilizing WiFi NICs capable of achieving near-Gbps data rates for a single spatial stream without altering the RF designs. LiRF paves the way for seamlessly integrating VLC into upcoming IoT networks, supporting high-speed, low-latency applications like Virtual Reality and Augmented Reality.","PeriodicalId":13204,"journal":{"name":"IEEE Photonics Journal","volume":"16 5","pages":"1-13"},"PeriodicalIF":2.1,"publicationDate":"2024-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10646482","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142137561","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In recent years, with the rise of deep neural networks, there has been significant progress in improving object detection accuracy. However, despite the state-of-the-art methods being tested on public datasets, there still remains a considerable gap when applied to real-world scenarios. This is because there are many unknown types of damaged samples in industrial object detection, the scale of the types varies greatly and the position changes are complex. Many previous works focus on rotating object detection and improve it, but this paper mainly combines the prior knowledge in remote sensing and industrial scenes, and the research is more general. To fill the shortage of wrapper datasets, we established a Carton Packing Tape (CPT) Dataset with a large scale of images only containing cartons. Specifically, we first collect a large number of images of packaged cartons from the real packaging production line and provide detection boxes for them by manual labeling. We have observed that the contextual clues required for different object detection tasks exhibit inconsistency. Furthermore, targets in varying backgrounds necessitate different receptive fields, which can be dynamically adjusted using different convolutional kernels. The features naturally attended to by these receptive fields of different scales should possess a unified representation disentanglement. Based on these insights, we propose a pioneering object detection method tailored for industrial environments, termed as oriented R-CNN with disentangled representations (ORDR). The experimental results indicate that our proposed method outperforms better than some of the state-of-the-art detection techniques available.","PeriodicalId":13204,"journal":{"name":"IEEE Photonics Journal","volume":"16 5","pages":"1-11"},"PeriodicalIF":2.1,"publicationDate":"2024-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10648834","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142181477","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The long exposure time of the image sensor is usually required for a good signal-to-noise ratio, which brings the time delays into the control loop of the fast-steering mirror. As a result, a low control bandwidth is insufficient to compensate for FPAT disturbances. In this paper, a time delay compensation-based disturbance observer (TDC-DOB) is proposed to reject carrier disturbances. This new TDC-DOB is plugged into the original feedback control loop, so the disturbance rejection can be optimized by designing an appropriate delay compensation controller. An improved TDC-DOB controller is presented to reject the widespread carrier disturbances, and also reduce the amplifications induced by the waterbed effect. This proposed controller can achieve a satisfying disturbance rejection beyond the closed-loop bandwidth which breaks the limitation of the existing DOB method. Both simulations and extensive experiments are carried out to demonstrate that the TDC-DOB method can earn a significant improvement for the disturbance rejection in comparison with the conventional feedback controller.","PeriodicalId":13204,"journal":{"name":"IEEE Photonics Journal","volume":"16 5","pages":"1-10"},"PeriodicalIF":2.1,"publicationDate":"2024-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10648825","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142143842","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, these costs are alleviated by optical access networks using general-purpose devices related to software-defined networking (SDN) and network function virtualization (NFV). We have studied physical layer virtualization to bring the advantages of SDN and NFV in optical access networks. We have focused on digital coherent technology to enhance capacity and extend reach within optical access networks. However, the future virtualized coherent access faces stringent frequency characteristics and the impact of chromatic dispersion (CD). The number of taps of finite impulse response (FIR) filters in the receiver increases rapidly for the CD compensation. The previously proposed DSP algorithm may not operate in this situation because the processing time exceeds the requirement. Therefore, this paper proposes and implements software for a lightweight multi-input-to-multi-output (MIMO) adaptive equalizer that separates FIR filters depending on the tap update period. The proposed method uses two types of FIR filters; one is used for polarization demultiplexing with short taps, and the other is a filter with long taps for the compensation of the CD in the fiber channel and the frequency distortion from the transceiver. Owing to filter separation, the calculation cost can be reduced. We indicate the processing time meeting desired requirements through real-time transmission experiments, even with increased taps. Additionally, we conduct offline simulations and experiments at a higher symbol rate than the real-time experiment.","PeriodicalId":13204,"journal":{"name":"IEEE Photonics Journal","volume":"16 5","pages":"1-7"},"PeriodicalIF":2.1,"publicationDate":"2024-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10643262","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142181478","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper explores novel applications of RoF systems in enhancing phased array antenna (PAA) performance for multi-channel wireless communication applications through the modulation instability (MI) phenomenon. Utilizing fibers experiencing MI with varying group velocity dispersions (\u0000<inline-formula><tex-math>$beta _{2}$</tex-math></inline-formula>\u0000) of −20, −11.3, −3.2, and −2 \u0000<inline-formula><tex-math>$text{ps}^{2}/text{km}$</tex-math></inline-formula>\u0000, the RoF system achieves operational flexibility across distinct central frequencies of 12, 16, 30, and 38 GHz, respectively. This approach represents a significant advancement in wireless communication technology, leveraging MI gain and an MI-based control system architecture to enhance performance across diverse frequency bands. The study investigates the impact of MI on modulation efficiency, presenting experimental results validating the feasibility and effectiveness of the proposed approach. The maximum MI gain by employing a 30 km fiber under MI is 18 dB, experimentally. Further optimization, achieved by increasing the fiber length to 45 km and adjusting nonlinear parameters and input power, demonstrates a remarkable MI gain of 38.1 dB. MI-based true time delay (TTD) techniques also address beam squint challenges, enhancing beamforming capabilities. The findings suggest that integrating MI into RoF systems holds excellent potential for improving wireless communication capabilities with reduced costs and space requirements compared to conventional methods. This research contributes to the growing body of knowledge in the field of RoF systems and offers insights into their practical applications in modern wireless communication networks.","PeriodicalId":13204,"journal":{"name":"IEEE Photonics Journal","volume":"16 5","pages":"1-13"},"PeriodicalIF":2.1,"publicationDate":"2024-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10640232","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142165106","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Taking into account the current research status of watermarking algorithms, a chaotic system is employed to bolster the security of the entire process. The experimental results indicate that the calibration algorithm exhibits strong universality and high accuracy. In comparison, the mean square error of the proposed rotation angle estimation model rose from 0.042 to 0.018, and the mean absolute error climbed from 0.065 to 0.032. With this enhancement, the robustness of color image watermarking algorithms against geometric attacks has taken a significant leap forward, the normalized correlation coefficient of quantization watermarking algorithm, which could not resist rotation attack, is now stable above 0.9.
