说明：  该程序包里包括了很多跟小波变换有关的经典算法，希望学习小波的朋友可以在其中找到你们需要的代码(The package includes many, many related to the classical wavelet transform algorithm, wavelet friends want to learn can find the code you need)

说明：  GSM TCH全速话音信道仿真（基带），包括内外编码，交织(TCH full speed GSM voice channel simulation (baseband), including internal and external encoding, interleaving)

matlab的gui教程，非常详细，简单易懂，便于学习，非常适合新手入门(The gui matlab tutorial, very detailed, easy to understand, easy to learn, very suitable for beginners)

进行OFDM系统的matlab仿真，其中采用的子载波数为8个。并且仿真了多普勒频移对OFDM的影响。基带调制采用QPSK(Matlab simulation for OFDM system, which USES the subcarrier number is eight.And simulation of the doppler shift effect on OFDM.Baseband using QPSK modulation)

直接将秘密图像的高4bit隐藏在RGB载体图像的R,G,B层中所选的那一层的低4bit(Directly to the secret image hidden in the high-4bit RGB vector images R, G, B layer, then a layer of selected low-4bit)

matlab编写的视频监控采集和目标提示软件，请批评指正！！！(matlab prepared video surveillance and target acquisition software tips, please criticism! ! !)

WGS-84 -> ECEF ECEF -> WGS-84 极坐标系 -> ECEF ECEF -> 极坐标系(WGS-84-> ECEF ECEF-> WGS-84 polar-> ECEF ECEF-> polar)

通过图像像素点之间的相关性来判断该像素点为噪声点还是信号点，进而对其进行滤波。(first, we judge the image pixel that it is noise pixel or signal pixel by compute the correlations between them.then we remove the noise of the image.)

说明：  混沌性质识别判别程序，以duffing系统为例，有详细源代码(Chaotic nature of identification procedures for identifying,)

主要是用c语言实现matlab中的fftshift函数的，(Mainly used c language matlab in fftshift function,)
