practicePWE1

计算器设计，其中包括加号输入、小数点的输入、及数字输入和求解。(Calculator design, including the plus input, the decimal point input, and digital input and solution.)

matlab学习材料，相关编程仿真，可能对初学者有用(matlab learning materials related to simulation programming, may be useful for beginners)

扩频通信系统的方针，源码比较详细，并且还包含对扩频通信系统的干扰技术研究(The principle of spread spectrum communication system, the source in more detail, and also includes the interference of spread spectrum communication system technology research)

Modulation test for OFDM : This is a set of five (5) codes about COFDM (Coded Orthogonal Frequency Division Multiplexing) and coding schemes such as Convolutional, BCH, Reed Solomon (RS) and Low Density Parity Check (LDPC). The study uses an OFDM signal over an AWGN Channel with white Gaussian noise model, and calculate the Bit Error Rate wich is plotted.

说明：  本文章详细介绍了 如何用matlab 进行小波分析从而建立音频的数据索引(This article details how to use matlab wavelet analysis carried out so as to establish audio data indexing)

说明：  人体心电信号的滤波，用一个Butterworth低通滤波器，滤除50Hz工频噪声，并采用不同阶数的Butterworth低通滤波器，比较效果(Human ECG signal filtering, using a Butterworth low-pass filter, filter the 50Hz frequency noise, and different orders of Butterworth low-pass filter, compare results)

说明：  通过matlab实现图像的逆滤波、维纳滤波的方法，效果还不错，很简单(Through matlab image inverse filtering, wiener filtering method, the effect is good, very simple )

数值计算，能够计算方程组，矩阵，能够自己输入数据进行计算(Numerical calculation, to calculate equations, matrices, to make their own input data calculation)

This code is used to cut selected part of the image that is of course after you decompress.   And run the code in the image circle separated.
