该程序是一个完整的模拟信号数字化传输系统的程序，它进过了PCM编码，2FSK调制解调和一个高斯白噪声，并有误码率的测量(The program is a complete program for the analog signal digital transmission system, it been to the PCM coding, 2FSK modem and a Gaussian white noise, and BER measurement)

学习matlab，适合初学者，自学Matlab必备的60个小程序代码(Learning matlab, suitable for beginners, 60 small self-Matlab essential program code)

this code is for compressing jpeg images in matlab.

峰值信噪比（PSNR），一种评价图像的客观标准。水印提取判断效果。(Peak Signal to Noise Ratio (PSNR), objective criteria for evaluating image. Determine the effect of watermark extraction.)

基于非局部均值图像去噪，对高斯加噪声有很好的去除效果，其中的修改程序，加入了对称处理，处理对称图像效果更好(Based on non-local means image denoising, the high Alaska noise removal, which modify the program, joined the symmetrical treatment, processing symmetrical image effect better)

gold序列用于跳频通信，给出了gold序列生成跳频序列的生成函数，并给出高斯白噪声和多用户干扰下的误码率曲线。(gold sequence for frequency hopping communications, give the gold sequence generated hopping sequence generation function, and to give white Gaussian noise and multi-user interference of the bit error rate curve.)

对采集到的信号进行快速傅里叶变换，可以实现对信号频谱分析(The collected signals fast Fourier transform, spectral analysis of the signal can be achieved.)

Microstrip antenna calculation

K-均值算法的Matlab源代码，比较简短(Matlab source code of K-means algorithm )

This is a program to extract the drum sounds (bass) from a music file. You can replace the "windycity.wav" file with any other .wav file you want.
