瑞利衰落信道（Rayleigh fading channel）是一种无线电信号传播环境的统计模型。这种模型假设信号通过无线信道之后，其信号幅度是随机的，即“衰落”，并且其包络服从瑞利分布。(Rayleigh fading channel (Rayleigh fading channel) is a radio signal propagation environment, the statistical model. The model assumed that after the signal through the wireless channel, the signal amplitude is random, that is, " fading" and subject to its Rayleigh distribution envelope.)

结构可靠度编程2个大的例题，以及对于电算MATLAB代码(The structural reliability programming two examples, as well as for the job Computing MATLAB code)

3 MATLAB functions for simulation of OFDM signal in Rayleigh fading channel. Including models for OFDM frame generating, cyclic prefix, pramble, as well as model for Rayleigh channel, QAM modulation function and a example of test process.

利用双线性变换法，设计一个0.4dB截止频率为10kHz且在30kHz处有最小阻带衰减为50dB的数字巴特沃兹低通滤波器，其抽样率为100kHz。利用教材（4.35）式求解原型模拟滤波器的阶数，并利用Matlab的M文件buttap设计模拟原型滤波器。用M文件bilinear将模拟滤波器传输函数变换成期望的数字传输函数。请用Matlab画出其增益和相位响应，并给出设计的具体步骤。(fuck!!!)

该程序可以实现图片的拖拽，放大和缩小等简单的处理。(The program can drag images, zoom in and out such simple treatment.)

PdfParse 用于从PDF文件中抽取文本数据的示例，支持unicode字符集编码、8进制和16进制编码。(PdfParse used to extract text from a PDF file example of data, unicode character set encoding, octal and hexadecimal encoding.)
