In this thesis, we will mainly do research on the novel scheme for Digital image Steganography, Digital Image Secret Transmission in network and the development of the information hiding device for application. The main contributions of this thesis are as following: The novel conversion method for mapping image to complex number is proposed, and the plus, minus, multiply and complex conjugate operation of image are defined based on Positional number systems and complex number system. Following new results have been gotten: 1 The suitable complex number basis to be used to express integers is a big set. 2 Any image can be mapping into a one-to-one point. 3 Lots of image processing problem can be considered based on geometric theory.

在本论文中，研究工作集中在数字图像伪装算法的新模型、图像在网络中的加密传输的新方案和信息伪装设备的研发等三个方面，主要包括：基于位值制记数法和复数系理论，提出利用复数作为基底的数字图像新的表示方法，用复数运算定义了图像和图像间的"加"、"减"、"乘"、"共轭"等运算关系；得到理论结果： 1、能表示任何整数的复数基是很大的一个集合。2、任何一幅图像，都能和复平面上的一个点一一对应。3、可以将图像问题化归为平面几何问题处理。4、复数系下的图像表示适合用于信息伪装。

In the traditional GSM network planning, the revised Hata model serves as the prototype, and the coefficient in the model formula is tuned according to the data obtained in the radio propagation feature test specific to local actual radio environment, so as to obtain the propagation model for practical prediction. A common digital map only contains the clutter information and the digital terrain model information. So the building designers cannot fully allow for the influence of radio propagation, and can only estimate the influence on the building roughly from a traditional perspective, e.g., consider the influence of different clutters through certain clutter offset.

在传统的GSM网络规划中，一般都以修正的Hata模型为原型，再利用规划软件通过导入针对当地的实际无线环境做无线传播特性测试所得的数据对模型公式中的系数进行修正而得到实际预测用的传播模型，一般使用的数字地图仅包括地物信息和高程信息，因此建筑物对无线传播的影响无法充分考虑，只能从统计意义上对建筑物的影响进行粗略的估计，如通过一定的地物偏移来考虑不同地物的影响。
