Bulid-Custom-Block-in-SIMULINK

Software-defined radios (SDRs) have been around for more than a decade. The first complete Global Positioning System (GPS) implementation was described by Dennis Akos in 1997. Since then several research groups have presented their contributions.We therefore find it timely to publish an up-to-date text on the subject and at the same time include Galileo, the forthcoming European satellitebased navigation system. Both GPS and Galileo belong to the category of Global Navigation Satellite Systems (GNSS).

程序模拟的是潜水艇这类大的铁磁性材料穿过海域对电磁场（地磁场）带来的变化以及如何通过物理手段消除这种变化(Program to simulate the submarine through the ferromagnetic material of such a large area of electromagnetic fields (magnetic field), and how the changes brought about this change through physical means to eliminate)

说明：  用MATLAB实现PCM（脉冲调制）的编码，其中调制采用的是mu律算法模型，量化间隔可以自行选择(Using MATLAB realization of PCM (pulse modulation) encoding, in which modulation is used mu law algorithm model to quantify the interval may choose)

dct隐写技术matlab实现资料。算法原理：通过在一个图像块中调整两个DCT系数的相对大小，隐藏秘密信息。 将载体图像分为8×8的块，做二维DCT变换 用来表示选中的两个系数的坐标对于第i bit秘密信息 if（要隐藏信息‘1’） make else make 逆DCT变换，还原图像 (dct steganography matlab implementation information. Algorithm principle: an image block by adjusting the relative size of the two DCT coefficients, hidden secret information. The vector image is divided into 88 blocks, making two-dimensional DCT transform coefficients used to represent the coordinates of the selected two for the first i bit secret information if (to hide information ' 1 ' ) make else make the inverse DCT, restore image)
