noise reduction in matlab this code is developed by syamsundar

i dont know what there in it exactely but you ca check

code warrior for windows set up for coding in code warrior

图像处理，学习matlab的源代码，转自国外(image processing, study the source code of Matlab, decanted from abroad)

快速傅里叶变换 (FFT) 实现，给定信号x(t)=sin(2πf0t)，f0=50Hz，对x(t)以fs=200Hz进行抽样，抽样点数为N=16。编写程序实现对x(n)的快速傅里叶变换，求得相应的X(K)。(Fast Fourier Transform (FFT) to achieve a given signal x (t) = sin (2πf0t), f0 = 50Hz, for x (t) with fs = 200Hz sampling, the sampling points is N = 16. Procedures for the preparation of x (n) of the fast Fourier transform, obtained by the corresponding X (K).)

this file content simple example about modulation bit stream.the type of modulation is (FSK,PSK and ask) after modulation data send and received after that show the relationship between signal to noise ratio (snr) and the bit error rate (ber).....

ar算法的matlab源程序的验证，对于随机过程的信号处理有所帮助(ar algorithm matlab source of verification, for random processes signal processing help)

说明：  标准极坐标牛顿潮流，包含导纳矩阵生成过程，以中国电力出版社出版《电力系统分析计算机算法》例题2.1为算例(Standard polar coordinates NEWTON, including admittance matrix generation process, with China Electric Power Publishing House &quot power system analysis computer algorithms,&quot Example 2.1 as an example)

通过用matlab程序设计实现IIR高通数字滤波器。(By using matlab program design of IIR high pass digital filter. )

本例是基于OFDM系统模型下的信道估计，根据不同信道估计进行的信噪比性能比较。(This example is based on the channel estimation OFDM system model, noise performance depending on a channel estimation performed comparing.)
