Description: 针对多聚焦图像融合，本文首先介绍了小波变换融合算法，虽然小波变换方法无冗余，高频分量损失较小，具有较好的融合效果，但存在两个主要缺点：一是移变性，二是融合图像在重构时会受到一些外来因素的影响，所以仍会丢失一些边缘信息，为了克服小波变换法的以上缺点，可以采用基于小波分解和点扩展函数模型PSF相结合的融合方法。该方法首先对不同的图像进行无降2采样的小波分解，以保持与源图像大小相同，然后分别将其各方向、各尺度的高频分量进行叠加，并依此提取其高频分量的特征信息来判定清晰目标或模糊目标，以此来设计融合算法，采用一定的策略将两副源图像进行融合，从而避开了小波的反变换，因此融合后的图像具有比小波变换法更好的融合效果。-multi-focus image fusion, this paper introduces the wavelet transform algorithm, Although the wavelet transform non-redundant, the loss of high-frequency components are smaller, better integration effect, But there are two major drawbacks : First, the shift variability and the second is the integration of image reconstruction will be subject to a number of external factors. Therefore, there would still be some marginal loss of information, in order to overcome the wavelet transform of the above shortcomings, can be used based on wavelet decomposition and the point spread function PSF model combining the fusion method.

Description: 基于OFDM的无线宽带系统仿真It contains mainly two parts, i.e. link-level simulator and system-level simulator.
Link-level simulator focus on a single-cell single-user scenario, where signal is transmitted from tx, and estimated at rx. Comparing the difference in tx/rx signal, the error rate can be found out. The output of the link-level simulator is the BLER/BER vs. SNR mapping table, that can be used for the system-level simulation.
System-level simulator focus on a multi-cell multi-user scenario. For the sake of simplicity, it takes the mapping table aquired in the link-level simulation, measure the actural SNR, and finds the corresponding error rate.-OFDM-based wireless broadband system simulation It contains mainly two parts, ie link-level simulator and system-level simulator.Link-level simulator focus on a single-cell single-user scenario, where signal is transmitted from tx, and estimated at rx .

Description: A few months ago, I was asked to develop a combo box that contains a tree view inside it. Initially, I used a normal tree view control, but I soon realized that I was short of space on some of the win forms. Now, in another project, I needed to use a multi select combo box, so I transformed the old tree view combo into a generic combo so that in the future I can add any control (for example, grid view, tree view, list box or any user control) inside the combo. In this article, I will focus on Multi-select and tree view combo but in the attached file you can find some more examples of this generic approach. I hope this article will be helpful for you.

Description: Image fusion is a process which combines the data from two or more source images from the same scene to
generate one single image containing more precise details of the scene than any of the source images. Among
many image fusion methods like averaging, principle component analysis and various types of Pyramid
Transforms, Discrete cosine transform, Discrete Wavelet Transform special frequency and ANN and they are the
most common approaches. In this paper multi-focus image is used as a case study.
