training a neural networks using error back propagation algorithm

产生rand，本代码主要介绍产生rand的主要步骤，非常简单有很明了，非常适合阅读 (Rand, the code describes the main steps of Rand are very clear, very simple, very suitable for reading)

说明：  利用双线性变换法设计一个级联型的椭圆IIR滤波器，对一段含噪语音信号进行滤波去噪处理并根据滤波前后的波形和频谱分析滤波性能。本课程设计仿真平台为MATLAB7.0，开发工具是M语言编程。首先在Windows下用录音机工具录制一段语音信号，并人为加入一单频噪声，然后对信号进行频谱分析以确定所加噪声频率，并设计滤波器进行滤波去噪处理，最后比较滤波前后的波形和频谱并进行分析。(Bilinear transformation method is used to design a cascade elliptic IIR filter, for a period of noise speech signal filtering denoising processing and according to the waveform and spectrum analysis of filtering performance before and after filtering. This course design simulation platform for the MATLAB7.0, development tools is M language programming. First under Windows tool to record a voice signal, a tape recorder and deliberately added a single frequency noise, and then the signal to determine the added noise frequency spectrum analysis, and design the filter for filtering denoising processing, finally compared before and after the waveform and spectrum of filtering and analyzed. )

说明：  使用快速傅里叶逆变换，分析离散时间信号中频率分辨率和信号的样本数之间的关系，并通过不同的滤波器进行对比。(The relationship between the frequency resolution and the number of samples in the discrete-time signal is analyzed by using the inverse fast Fourier transform, and compared by different filters.)

关于多径信道的matlab的子函数实现，Jakes模型等都包含(On the multi-path channel to achieve the matlab s Functions, Jakes model contains all)

说明：  this is very good for master students and use in communication system course
