射频信号的去噪，纯净信号为数字调制的AN,FM,BPSK信号，噪声为高斯白噪声。应用SVD分解方法进行去噪。(RF signal denoising, pure signal for the digital modulation of the AN, FM, BPSK signals, noise is Gaussian white noise. Application of SVD decomposition method for denoising.)

为研究局部阴影效应对光伏发电系统的影响，首先建立了光伏阵列工程数学模型，分析局部阴影条件下光伏阵列的输出特性。为了便于工程分析，该文利用PVSYST软件分析比较单晶硅、多晶硅和薄膜电池等3种不同材料光伏电池在局部阴影条件卜的输出功率，为工程应用提供了良好的指导作用。最后提出了几种提高光伏阵列抗局部阴影能力的措施厂 (To investigate the effect of local shading effects on photovoltaic systems, photovoltaic array project was first established mathematical model to analyze the output characteristics under conditions of partial shading of the PV array. In order to facilitate engineering analysis, this paper use PVSYST software analysis and comparison monocrystalline, polycrystalline and thin film batteries, photovoltaic cells of three different materials in partial shade conditions Bu output power for engineering applications provide a good guide. Finally, several photovoltaic arrays to improve the ability to measure resistance to partial shade plant)
