线性调频信号的回波仿真，比较特别的是对近距目标的仿真(the stimulation of Linear fm signal wave , particularly to the close goals )

这是HMM的语音识别不用修改就可以使用，很好用希望大家喜欢(This is a HMM speech recognition can be used without modification)

UILDING THERMAL PERFORMANCE ANALYSIS BY USING MATLAB/SIMULINK

Pulse width modulation - matlab simulation.

基于matlab的画出一个不完整的椭圆，结果完美。只要稍作修改可以出来任意要求范围的不完整椭圆。(Matlab to draw the ellipse )

很经典的书籍哦，有1200多页，非常经典的概率图模型书籍，网上价格一般都1000多元哦！(it is very good for you!)

产生北斗卫星伪随机码程序，利用该程序可以产生任意一颗北斗卫星的C/A码序列。(Pseudo-random code generation Beidou satellite program, use the program can generate any one Beidou satellite C/A code sequence.)

基于 DCT(离散余弦变换 )域的信息隐藏算法是目前应用最广的变换域算法 ,此类算法的最大不足是嵌信息量小。通过分析 DCT域隐藏算法隐藏容量少的原因 ,提出了一种大容量的 DCT域信息隐藏算法。算法首先对载体图像进行频谱均匀化处理 ,然后对图像进行全局 DCT变换 ,并将隐藏信息嵌入到载体图像的低频 DCT系数上 ,信息嵌入采用分段量化的方法实现 ,提取隐藏信息时不需要原始载体图像。实验结果表明 ,该算法的嵌入容量大 ,不可感知性好。(Based on DCT (discrete cosine transform) domain information hiding algorithm is the most widely used transform domain algorithms, the largest of these algorithms is the lack of a small amount of information embedded. Hiding Algorithm for DCT domain by analyzing the hidden reasons for the low capacity, a large capacity of information hiding algorithm for DCT domain. Firstly, the spectrum of the carrier image homogenization, and then the image is a global DCT transformation, and hidden information embedded into the image of the low-frequency DCT coefficients, the information embedded in the methods used to achieve sub-quantization, extract hidden information without the original Vector image. Experimental results show that the algorithm embedding capacity, can not be perceived good.)
