频谱感知中的能量感知算法，在不同虚警概率的情况下，信噪比和检测概率的变化。(In Cognitive Radio， spectru sensing is important。And energy detection is more. In different false alarm probability, the Pd vary with the SNR.)

复制看跌期权,主要包含期权结构、收益分析的内容(copy a put option)

说明：  lena图像的分解将规范化后的图像的数据格式由适合显示图像的uint8格式转换为适合数值处理的double格式，再调用二维小波分解函数进行图像分解，最后为了清晰地显示分解图像的塔式结构，在图像的相应区域绘制若干分界线。 (lena image after decomposition of the standardized image data format suitable for display by the image is converted to uint8 format suitable for numerical treatment of the double format, and then call the function of two-dimensional wavelet decomposition for image decomposition, and finally in order to clearly show the decomposition of the image of the tower structure , the corresponding region in the image number of the line drawn.)

Introduction to Matlab Image Processing include the vector arrays, matrix manupulation, inputs and outputs and plotting in general and 2d and functions & Iterations

以某些特殊函数为基将数据过程或数据系列变换为级数系列以发现它的类似频谱的特征，从而实现数据处理。(In certain special functions as the base data process or data series is converted into the series at a similar spectrum to find that it features, in order to achieve data processing.)

说明：  实现图像的正反傅里叶变换，并用fft实现两幅图像的幅相交换(Amplitude and phase s replacement with fft)

利用MATLAB编写了stokes2求解波浪压力分布，即在动水压力分布和总压力分布，在港口海岸设计中用重要地位。(sove stokes pressure of wave)

Manages the interaction between the secure system setting for default geolocation.

由于硬判决在判决过程中将接收直接判决为[1 0],而损失了相应的近似信息，导致了接收信息在某种意义上的浪费。软判决将接收电平量化，尽可能保存相应的信息，故可以提高译码性能。(soft descision decoding)
