Detection Algorithm of Support Vector Machine for Four-Level Free-Space Laser Communication Signals
Hongwei He, Zhihang Wu, Zhaoxin Yu, Xianglian Feng, Hexin Jiang, and Shiming Gao
A detection algorithm based on support vector machine (SVM) is proposed for four-level pulse amplitude modulation (PAM-4) signals in free-space laser communication. Using the power spectral density inversion method, we simulate the atmospheric phase screen. Under the assumption of Taylor frozen flow, we obtain the opti

System Signal-to-Noise Ratio Analysis of Hyperspectral Imaging Chain Model Based on Electron Multiplication
Da Yu, Jinguo Liu, Xin He, Jiawei He, Jiayu Chen, Xiaoyang Zhang, and Chang Peng
The application effect of hyperspectral imaging relies heavily on the acquired signal-to-noise ratio (SNR) of images. The hyperspectral imaging requires a high frame rate and a low SNR for a high spatial resolution. The time-delay-integration (TDI) mode cannot be used to solve the problem of weak light energy, because

Wei Yi, Yong Zeng, and Zheng Yuan
Among the existing synthetic-aperture radar (SAR) satellites, the GF-3 offers the most kinds of imaging modes. The fusion of the GF-3 SAR images with the multi-spectral images can improve the visual quality of the SAR images. We show how to use the nonsubsampled contourlet transform (NSCT) for simulating high-resolutio
