matlab源代码，很适合大家的学习，对大家很有帮助。(matlab source code, it is suitable for everyone to learn, very helpful to everyone.)

多普勒二维频谱分析，通过载入数据得出而为多普勒频谱(2D Doppler spectra)

学习Matlab的仿真工具，而且有丰富的例子供大家参考(learning Matlab simulation tool, but a wealth of examples for your consideration.)

two way relay channel channel estimation(two way relay )

add a noise to a watermarked audio signal to test the robustness input : vector representing the watermarked audio file & the desired SNR output : vector representing the noisy watermarked audio file

This code is an interesting version of noise production. this produced noise in controlled manner to display clouds. same code may be used to develop several natural random phenomenon

说明：  使用统计的方法来实现纹理特征提取，很有用的一个方法(Use statistical methods to achieve the texture feature extraction, a method useful)

非平稳噪声下，通过预处理，可以很好的消除噪声的影响，且能对信号解相干(Non stationary noise, through pretreatment, can be very good to eliminate the influence of noise, and to signal decorrelation )

resistive and inductive load. simulation also demonstrate the role of free wheeling diode. Single phase pulse generator was developed to generate the pulses at required firing angle.

正交频分复用(OFDM)技术及其MATLAB模拟(orthogonal frequency division multiplexing (OFDM) technology and its MATLAB simulation)
