这是关于蓝牙跳频通信系统的仿真设计，利用MATLAB的SIMULINK仿真模型，分为跳频系统传输部分、FH-CPM Modulaor子系统、信号接受部分、FH-CPM Demulator子系统、Dis-assemble Packet子系统、频谱分析模块、误码分析模块共七个模块，共有6个MDL文件。(This is about the Bluetooth frequency hopping communication system simulation design, the use of MATLAB-SIMULINK simulation model is divided into frequency-hopping system transmission parts, FH-CPM Modulaor subsystem, signal receiving part, FH-CPM Demulator subsystem, Dis-assemble Packet sub- system, spectral analysis module, the error analysis module of seven modules, a total of six MDL file. )

说明：  有图像分割的各种算法：分水岭 最大类间 最大熵法等等源程序(With image segmentation algorithms: the watershed between the largest class of maximum entropy source, etc.)

由于实际信道中的多径和阴影效应，单个认知用户频谱感知的性能受到影响，因此需要靠不同用户间的协同频谱感知来对抗多径和阴影效应。本设计要求在文中采用一种协作机制，即两用户进行协作频谱感知，提高主用户的检测率，减少检测时间，并且得到捷变增益。要求给出仿真结果。(As the actual channel of the multi-path and shadow effect, a single user of spectrum sensing of cognitive performance are affected, it needs to depend on collaboration between different users of spectrum sensing to combat multipath and shadow effects. The design requirements in the text using a cooperation mechanism, namely, two user collaborative spectrum sensing, to improve the detection rate of the primary users, reducing detection time, and get agility gain. Required to give simulation results.)

该文件是介绍卡尔曼滤波算法的，整个设计过程和思路明晰。(The document was introduced Kalman filtering algorithm, the whole design process and clear thinking.)

有详细的注释，利用matlab写成的窄带噪声发生，能量谱分析计算。( There are detailed notes, Using matlab written narrowband noise occurs, Energy spectrum analysis and calculation.)

此程序为OSIC-MMSE程序，可用于多天线分层解码。(order SIC-MMSE program)

Optical Character Recognition

椭圆滤波器C程序和matlab的仿真m文件，根据matlab仿真设计椭圆滤波器参数，再编写C程序(C program of ellipsefilter)
