VC++和 Matlab 的 混 合 编 程 具 有 很 大 的 实际意义。 文 讨 论 了如何 使 用 Matlab 的 Complier 将 *.m 函 数 编 译 为 动 态 链 接 库 DLL， 提 供 给 VC++调 用 的 方 法，提 供 了 一 种 VC++与 Matlab 混合编程的 快 速 实 现 。(The mixed programming of VC++ and Matlab has great practical significance. This paper discusses how to use COMplier of MATLAB to compile *. m function into DLL of dynamic link library and provide a method for calling VC++. It also provides a fast realization of mixed programming between VC++ and MATLAB.)

VGA驱动及显示程序，用Verilog编写代码实现VGA的驱动和显示，并且提供了测试程序Testbench通过测试能得到正确的时序波形。(the source code for driving VGA and displaying the images,the testbench was offered.)

STIM300高精度IMU的输出解码程序，MOD93格式，带CRC校验，直接可以运行(MOD93 format with a CRC check can be run directly)

主要是实现调制识别，区分几种常用的数字调制信号。含有两个文件夹 其一为特征参数的仿真；其二为正确识别率的仿真。文件夹key feature simulink中： 运行程序会得到各特征参数之间区分图 从图中可看到特征参数的有效性，见图。 文件夹classification rate simulink中：运行main.m文件 可以得到正确识别率 见图。(It is mainly to realize modulation recognition and distinguish several commonly used digital modulation signals. The simulation of two folders is one of the characteristic parameters, and the second is the simulation of the correct recognition rate. In the folder key feature Simulink: The running program will get the validity of the feature parameters that can be seen from the diagram, as shown in the diagram. Folder classification rate Simulink: running the main.m file can get the correct recognition rate.)

This thesis presents simulation data on array operation in wideband communication systems. It is shown that array structures with closer inter-element spacing outperform structures with much larger inter-element spacing. It is also shown that circular structures outperform linear structures. This performance dierence between the classications of arrays is due largely to the circular array s ability to handle high levels of interference. Even though a diversity combining scheme (MRC) was used in the simulator, the arrays provided interference rejection capabilities due to the closely spaced antenna elements.
