Orbital-Angular-Momentum Versus MIMO: Orthogonality, Degree of Freedom,and Capacity
Haiyue Jing, Wenchi Cheng, Xiang-Gen Xia +1
The plane wave based wireless communications have becoming more and more matured, along with the well utilization of the traditional resources such as time and frequency. To furthe…
A Simple Channel Independent Beamforming Scheme With Parallel Uniform Circular Array
Haiyue Jing, Wenchi Cheng, Xiang-Gen Xia
In this letter, we consider a uniform circular array (UCA)-based line-of-sight multiple-input-multiple-output system, where the transmit and receive UCAs are parallel but non-coaxi…
Excess Distortion Exponent Analysis for Semantic-Aware MIMO Communication Systems
Yuxuan Shi, Shuo Shao, Yongpeng Wu +3
In this paper, the analysis of excess distortion exponent for joint source-channel coding (JSCC) in semantic-aware communication systems is presented. By introducing an unobservabl…
LO-Det: Lightweight Oriented Object Detection in Remote Sensing Images
Zhanchao Huang, Wei Li, Xiang-Gen Xia +3
A few lightweight convolutional neural network (CNN) models have been recently designed for remote sensing object detection (RSOD). However, most of them simply replace vanilla con…
Symbol-wise Puncturing for HARQ Integration with Probabilistic Amplitude Shaping
Li Shen, Yongpeng Wu, Derrick Wing Kwan Ng +2
In this letter, we propose a symbol-wise puncturing scheme to support hybrid automatic repeat request (HARQ) integrated probabilistic amplitude shaping (PAS). To prevent the probab…
A three-dimensional dual-domain deep network for high-pitch and sparse helical CT reconstruction
Wei Wang, Xiang-Gen Xia, Chuanjiang He +2
In this paper, we propose a new GPU implementation of the Katsevich algorithm for helical CT reconstruction. Our implementation divides the sinograms and reconstructs the CT images…
