Matlab code for Derivative filter deisgn

多窗口法做功率谱估计的经典例子，由MIT的Peter Huybers所写(Multi-window method to estimate power spectrum, written by Peter Huybers of MIT)

this function is used for resizing the cropped images got the process of character extraction for the first step of build a ANN. This is useful because it can resize a lot of images in one folder.

编写了MATLAB程序生产和扩频码进行仿真，仿真程序从发送方完成通道的接收端，得出在不同的扩频码，在不同的信噪比即误码率的图形比较直接序列扩频通信系统原理，改善系统性能的度(Written MATLAB program to produce and direct sequence spread spectrum communication system principle of spreading codes for simulation, emulation program to complete the channel from the sender to the receiver end, draw graphics comparison at different spreading code, the bit error rate under different SNR i.e., the degree of improvement of the system performance)

包含收发两个客户端的链路级通信程序,DrIzten参数通过matlab代码，单径或多径瑞利衰落信道仿真，基于matlab GUI界面设计,EjbsXmo条件是路径规划的实用方法，表示出两帧图像间各个像素点的相对情况。( Contains two clients receive link-level communications program, DrIzten parameter By matlab code, Single path or multipath Rayleigh fading channel simulation, Based on matlab GUI interface design, EjbsXmo condition Is a practical method of path planning, Between two images showing the relative circumstances of each pixel.)

模式识别，聚类分析的最大最小距离算法算法Matlab演示(Pattern recognition, cluster analysis algorithm for the maximum minimum distance algorithm Matlab demo)

多种通信模式的仿真，由CONCORDIA UNIVERSITY的教授编制。(Simulation codes programmed by professor in Concordia University.)

SAR雷达多目标生成子函数，SAR雷达在斜视角etha下，雷达回波信号仿真 (multi targetes funcution)

帮助新手快速学习matlab，很容易上手的，是一些基础知识。(Help novices quickly learn matlab, very easy to use, is some basic knowledge.)

说明：  This code is related to the course Digital Communications. It reproduce the error probability as a function of the SNR per bit for 16-QAM. Enjoy it!
