reding the ECG signal information

说明：  使用matlab进行图象处理的经典命令.(picture command)

线性调频信号的脉冲压缩，合成孔径雷达（SAR）的第一个大作业的程序(the compression of chirp signal)

blocking probability for multi user detection to cancel interference

通过设置不同的参数利用Matlab软件仿真了不同场景下的系统性能 (This document suggests a user’s guide to a MATLAB application which simulates a Spatial Channel Model (SCM) based on reference [1] with some minor adjustments. It focuses on how to use the Graphical User Interfaces (GUIs) and the functions of the application and avoids going into specifics about the nature of the parameters as this is done analytically in the reference document)

对从金属棒材中提取的超声缺陷信号经过自适应滤波以后的极坐标显示图(polar graph of ultrasonic defect signal)

说明：  本文给出了用matlab实现简单UWB定位系统的所有代码，并可产生可视化的操作界面。(In this paper, simple to use matlab UWB positioning system all of the code, and can cause visual interface.)

t检验，通过多样的分析可以得出想要的熵结果。(t-test.you can download it every day.)

中心化后的傅里叶谱，傅里叶频谱和平均值,计算图像的平均值(Fourier spectrum and average value)

fsk调制解调及相应误码率计算。随机产生一正弦信号并进行相应的调制解调。(fsk modem and the corresponding bit error rate. Randomly generate a sinusoidal signal and the corresponding modem.)
