关于质心定位的matalab原代码，做定位方面毕设的人可以用！(Matalab centroid location on the original code, so positioning complete set of people can use!)

fft源代码,感觉代码不错，所以传上去了，希望对大家有帮助。(fft source code, can only pass one, so this is only passing on part of the other part of the horse uploaded in the past)

在matlab环境下编写的简易计算器，能够进行四则运算和正弦余弦，x的y次方运算，对数运算等相关运算(In the matlab environment prepare a simple calculator that can perform arithmetic calculations and sine cosine, x of y th arithmetic, logarithmic arithmetic operations and other relevant)

仿真研究2PAM，4PAM眼图特性； 分别加入高斯白噪声，码间串扰，研究它们对眼图的影响； 改变接收滤波器的滚降系数，研究它对眼图的影响； 研究不同波特率对眼图的影响。 (Simulation studies 2PAM, 4PAM eye diagram characteristics were added white Gaussian noise, inter-symbol interference, influence their study eye chart changing the receive filter roll-off factor, the study of its effects on the eye research on different baud rate eye effects.)

说明：  对变量DMC源程序，matlab语言。可以看看。(DMC source of variable)

认知无线电BPSK信号的循环平稳检测的性能仿真 包含信号循环谱图(Cognitive radio spectrum cyclostationary detection performance cycle)

HHT算法实现emd分解，及希尔伯特黄变换，实现瞬时频率瞬时幅值，边际谱的提取。(The HHT algorithm emd decomposition and Hilbert-Huang transform to achieve the instantaneous amplitude of the instantaneous frequency marginal spectrum extraction.)

说明：  BP算法的matlab实现，能较好的得到结果，误差范围较小(BP algorithm matlab implementation, can get better results, less error range)

this matlab code helps the image processing lerners to denoise grey images as well as other applications having denoising applications.

进行常用雷达信号的matlab仿真，分为线性调频信号的时域频域仿真和线性调频脉冲压缩处理2个部分。(Commonly used in radar signal matlab simulation, divided into linear FM signal in time domain frequency domain simulation and linear FM pulse compression of two parts.)
