Previous studies often address channel estimation and channel state information (CSI) implicit feedback issues in 5G new radio (NR) system independently, posing a challenge to achieve effective coordination between the two processes in a shared environment. Consequently, we propose a deep learning-based scheme that jointly addresses channel estimation and implicit CSI feedback. In this scheme, the received pilot information from user equipment (UE) is regarded as a two-dimensional image. Channel estimation is performed employing the ResMLP architecture, whereas the Transformer architecture is utilized for implicit CSI feedback. Furthermore, a novel training approach is introduced to further enhance the performance of the proposed scheme. Simulation results illustrate a substantial improvement compared to the reference scheme employed in the 3rd Wireless Communication Artificial Intelligence (AI) Competition (WAIC). © Chinese Institute of Command and Control 2024.

A three mode resonance antenna with stable radiation pattern is designed using characteristic mode analysis. The antenna is composed of two layers of substrate, the upper and lower metal surfaces of upper substrate are used to form substrate integrated waveguide cavity-backed slot antenna (SIW-CBSA) which constitutes microstrip patch. And the mode TM01 of patch and modes TE110, TE120 of SIW-CBSA have basically consistent radiation pattern performance based on characteristic mode analysis. The coplanar waveguide is applied to excite modes TE110 and TE120, which connects microstrip feedline with double-layer substrate thus excite mode TM01 of patch simultaneously. Simulation results show that impedance bandwidth better than -10dB is from 8.32 to 8.77GHz, and the radiation pattern is basically consistent in whole bandwidth. Prototype size of the scheme is 1.13λ0 × 0.79λ0 × 0.03λ0 (wavelength in free space). © 2023 IEEE.

Polarimetric Synthetic Aperture Radar (PolSAR) images have attracted much attention with abundant polarimetric scattering information. In recent years, many deep learning models have been proposed and highly expanded to PolSAR image classification. However, how to learn the complex matrix information is an indispensable problem. To address this problem, a Wishart Deeplab network is developed, which can not only learn the polarimetric matrix structure by designing Wishart network level but also learn multi-scale polarimetric scattering features by incorporating dilated convolution. Specifically, the Wishart-Deeplab based PolSAR classification model is constructed by designing the Wishart convolution operation to learn the statistical information of PolSAR data. Then, a deeplabV3 + network is followed to obtain the multi-scale semantic features by dilated convolution. By this way, statistical distrubtion-based and high-level semantic features are adaptively learned to improve the performance of the network. The experiments are conducted on two sets of real PolSAR data and results show that this method can obtain better classification results. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

This study investigated the application of near-infrared（NIR） diffuse reflectance spectroscopy for rapid and non-destructive detection of ash and sulfur content in coal powder. Partial least squares（PLS） regression models were established using NIR diffuse reflectance spectroscopy. Preprocessing methods included standard normal variate, first derivative,second derivative, and multiplicative scatter correction were discussed. The ash and sulfur content models processed with standard normal variate transformation outperformed. The experimental results demonstrate that the established models for ash and sulfur content have achieved satisfactory performance, with coefficients of determination（R） of 0.95 and 0.96, respectively,and root mean square error of prediction（RMSEP） of 0.68 and 0.18, respectively. The confirmation of NIR spectroscopy modeling for rapid detection of coal powder properties compared to traditional methods indicates faster speed and satisfactory precision, demonstrating its significant applicability in industrial process analysis. It has been confirmed that NIR spectroscopy modeling enables rapid detection of coal powder properties. Compared to traditional methods, it offers faster speed while meeting the required precision standards, demonstrating higher application value.

In semiconductor manufactuing, wafer bin maps (WBMs) with specific defect patterns provide valuable information on the root causes of process abnormality. The identification of these patterns is thus of crucial importance for yield enhancement and quality improvement. Existing studies have made great efforts to automatically classify the WBMs into predefined patterns. However, rarely occurred and mixed-type defect patterns are also generated due to the increasing complexity of the manufacturing processes. In this case, the conventional classification based method has its limitations. to solve this problem, this study aims to develop a novel approach to search similar WBMs for the identification of defect patterns and their potential causes. Tensor voting, which is a perceptual grouping approach, is considered to extract structural information from the spatial patterns. The modified best-buddies similarity (BBS) is applied to measure the similarity level. Experimental results demonstrate the effectiveness of the proposed approach in the similarity searching and identification of defect patterns. © 2022 IEEE.

Soft microrobots have garnered attention in the biomedical field due to their ability to access hard-to-reach regions within living organisms for precise manipulation. However, the inability to alter the stable morphology after design and fabrication remains a pressing issue for existing soft microrobots. This limitation results in a fixed range of locomotion modes, thereby restricting the diversity of operational environments. Addressing this challenge, this study proposes and designs a biocompatible X-shaped soft microrobot that achieves alterable stable morphologies through an innovative mechanism. We developed a deformable soft hydrogel robot based on alginate gel’s ability to reversibly swell in response to ion concentration changes. Based on the deformation characteristics of this microrobot, we have designed undulating and rolling locomotion modes that are suitable for different morphologies, along with their corresponding magnetic field manipulation systems, enabling multi-morphology locomotion of the robot. Experimental validations demonstrate that the designed flexible microrobot can achieve a deformation deflection angle of up to 150° under manipulation. This robot not only performs forward undulating locomotion in its expanded state but also executes rolling motion in its spherical configuration, exhibiting high locomotion flexibility and adaptability. © 2024 Copyright held by the owner/author(s).
