各种逆变方式的simuliink仿真（原创） 源码+总结文档(Various the inverter ways of simuliink simulation (original) source+ summary document)

這是一個讓原始音訊可以再不改變音訊長度下，改變pitch的程式，因為如果音訊用resample，雖然可改變其音訊頻率音高，但是卻會有拉長音訊的副作用，因此設計了一個可以改善其缺點的小方法(實做paper ）(This is an original audio so that you can no longer change the audio down the length of the program to change the pitch because if the audio with resample, although it can change the pitch of the audio frequency, but the audio will be stretched side effects, and thus can improve the design of a small way shortcomings (real do paper))

能够非常有效地在比较大的干扰下比较准确地反映真实值，如果观测端加入干扰较大时，卡尔曼滤波器能够较为有效地进行滤波，不过当状态端的干扰增大时，卡尔曼滤波器的滤波效果也会随之下降。(Can very effectively in the relatively large disturbances under more accurately reflect the true value, if the observation end joining interference is large, Calman filter can effectively filter, but when increasing the jamming state end when the filter effect of Calman filters will fall.)

同相中相环路，用于符号同步估计。采用simulink设计(PLL for bit/symbol synchronization )

it is a matlab file used to create figures for digital ofdm process

基于一个字嵌入水印0和1bit,原理是将图像转换到空间域后选择系数类嵌入水印，能抗打印扫描攻击(based on a word and embedding watermark 0 1bit, the principle is to convert the image into the spatial domain selection class watermarked coefficient, )
