用同态滤波的方法增强图像对比度，解决因为光照问题引起的图像模糊问题。(By homomorphic filtering method to enhance image contrast, to solve the problem because the light-induced image blurring problem.)

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)

利用阵列随机共振系统处理AM信号，比较处理前后的加噪信号波形，可以发现SSR系统具有抑制噪声的作用，(Stochastic resonance system using array processing AM signals, comparing before and after adding noise signal waveform, can be found SSR system has a noise suppression effect)

计算最大李雅普诺夫图，来分析微分方程的分岔情况(To calculate the largest Lyapunov Figure to bifurcation analysis of differential equations)

A dynamic estimation of channel is necessary before the transmission of the signals since the wireless channel is time–varying..we use MMSE method for channel estimation. The MMSE method calculates the following, MMSE channel estimator is designed to minimize the estimation MSE. The MMSE estimate the channel responses.
