image sharpening with psnr value

音频系统，coding, modulation, AWGN, 通过最小距离探测码元，解码，播放。根据不同的SNR，测试在多小的SNR情况下，人耳能识别音频。(Audio systems, coding, modulation, AWGN, by minimizing the distance detection symbol, decoding, playing. Depending on the SNR, the test in the case of multiple small SNR, the human ear can identify audio.)

this is how we can usingmicrocontroller with gsm modem to giving command opening our door

Dennis M.Sullivan FDTD书后matlab程序 已经调试验证 第一章第二章(Dennis M.Sullivan matlab program using FDTD book have been debug and verify)

一些关于MATLAB GUI设计的例程，值得借鉴。(Some of the routines on MATLAB GUI design, it is worth learning from.)

wigner时频分布，解压后在matlab中运行，处理信号时需要做希尔伯特变换！(function of wigner-ville distribution, may apply on analysis of seismic wave!)

This is material which include Fuzzycontrol theory and algorithms.

实现典型相关分析，计算加权加速度,基于chebyshev的水声信号分析，用于建立主成分分析模型，线性调频脉冲压缩的Matlab程序,相控阵天线的方向图（切比雪夫加权），鲁棒性好，性能优越。 ( Achieve canonical correlation analysis, Weighted acceleration, Based chebyshev underwater acoustic signal analysis, Principal component analysis model for establishing, LFM pulse compression of the Matlab program, Phased array antenna pattern (Chebyshev weights), Robustness, superior performance. )

说明：  有关于光学的MATLAB程序仿真，关于衍射，折射等光学现象(The optical MATLAB example can be used by beginners)

说明：  不调用matlab库函数，实现任意奇数方块模板，对其内数值进行中值滤波，包括对高斯，椒盐图的处理(Do not call the matlab library function, the realization of arbitrary odd-numbered box template, with its value for median filtering, including the Gaussian, salt and pepper map processing)
