二质量伺服系统的Simulink仿真程序(Quality servo system in Simulink simulation program)

完全符合IEEE802.11a的卷积编码和维特比译码，注释丰富，易于理解和调试。(this program is based on the principle of IEEE802.11a,which has necessary note and is easy to debug. )

说明：  实现分段函数的图形绘制，包括三角函数，直线等。对于初学者有一定的引导作用。(To achieve sub-function graphics rendering, including trigonometric functions, linear, etc.. For beginners there is a certain guide.)

该文件是我自编的FDTD 1D 2D 3D的入门MATLAB程序。然后包含一些贴片天线的代码。全是自编，点击可运行。(The files are the codes for FDTD coding including 1D 2D 3D using MATLAB. There are also codes for patch antenna modelling)

协作频谱感知虽然可提高系统的感知性能， 但随着感知节点数目的增加， 系统资源的占用越来越多， 系统传输效率下降． 分析了协作频谱感知方法的感知性能， 得到协作频谱感知的感知性能与感知节点数目和接 收信噪比之间的关系， 提出了一种新的次级用户节点的选择方法， 该方法有效保证了所选择节点的感知性能， 仿真验证了该算法的有效性和可靠性．(Although the cooperative spectrum sensing can improve the perceived performance of the system, but with the perception of the number of nodes increases, more and more system resources, the system transmission efficiency decreased. Cooperative spectrum sensing method of analysis of the perceived performance of collaborative spectrum sensing by the perception of performance and perception of the number of nodes and the relationship between the received SNR, a new secondary user node selection method, which effectively guarantee perceived performance of the selected node, the simulation proves the validity and reliability.)

说明：  删除新到下的LDPC度分布的matlab程序，帮助初学者进一步了解LDPC码的仿真。(Remove New LDPC degree distribution under the matlab program to help beginners learn more about the simulation LDPC codes.)
