It describes the fading in wireless channels

说明：  这是matlab编写的一组神经网络的程序,非常好用,只需要改动一些参数即可(It is written in a matlab neural network program, very easy to use, you can only change some parameters)

This is a procedure for computing small-world .For large complex networks, understandably, their sheer size is very important. This procedure is useful.

完美的ofdm系统matlab仿真程序，从编解码到加入信道到调制解调到信道均衡到同步和频偏估计，带有详细的程序说明(Matlab simulation ofdm system the perfect program to join from the codec to the modem channel to channel equalization to the synchronization and frequency offset estimation, with a detailed description of the procedures)

说明：  英国伦敦大学一个学生写的有关UWB的文章，里面有较详细的说明并附有Matlab源码，适合初学者。(University of London a student to write an article on UWB, there are more detailed description with Matlab source, suitable for beginners.)

介绍matlab的腐蚀，膨胀，开运算，闭运算，细化，去噪等的指令，对于初学者非常有用。(Introduction matlab corrosion, expansion, opening operation and closing operation, refinement, noise and other instructions, very useful for beginners.)

Ridgelet transform and curvelet transform

在无线信道的理论基础上，分析了Suzuki信道模型的结构原理，介绍了利用正弦波叠加法构成高斯序列，从而建立Suzuki信道数学模型的方法，并通过Matlab软件对其进行了仿真。(In the theory of radio channel based on the analysis of Suzuki channel model structure principle, describes the use of sine wave superposition method constitutes a Gaussian sequence, thereby establishing a channel model Suzuki method, and through its simulation Matlab software.)

包含九种图像评价函数，对图像进行清晰度判断并对比各种方法的时效(Evaluation function contains nine images, the image clarity and compared various methods of aging)

学习并找到降噪方法，对语音信号背景噪声做处理，使得声音更清晰。(The background noise is the most common factor degrading the quality and intelligibility of speech in recordings. Spectral subtraction can lower the noise level without affecting the speech signal quality. In this paper, we have studied and implemented to reduce the background noise of the voice signal, and to make improvements to reduce the background noise of the experiment. Not only with the spectral subtraction of the noisy signal of the transformation, we improve the traditional spectral subtraction based on the introduction of the parameters, by adjusting the parameters(α、β、γ) to achieve better enhancement.)
