说明：  femto是目前解决中心基站服务量大、性能低的一个热点方式，该方式可以提供弱信号地方好的通信质量，本代码就同频防干扰做出设计，希望对读者有用(Centre for Settlement of femto base station is the service volume, low performance is a hot way, the way to where weak signals can provide good communication quality, the code to make the same frequency anti-interference design, hope to be useful reader )

利用matlab，产生具有三个频率的跳频信号(the generation of jump-frequency signal)

STK软件平台对garada卫星系统的仿真,可见性，覆盖面积和经历时间分析(simulink of satellite system by STK )

包括完整的Turbo码编码和译码程序，可用于实验仿真和教学。主文件为一个测试文件，仅对一个Turbo码字进行译码。(The uploaded matlab files including the Turbo code encoding and decoding programs can be used for simulations and teaching. The main file is a test file, which only decodes one Turbo codeword.)

generate the gaussian noise

计算在N维空间中，两条线之间的最短距离，N可以是3或者3以上的任何数值(Calculated in N-dimensional space, the shortest distance between two lines, N could be any of 3 or more values 3)

一种小波增强图像的方法，过程详细，结果对比分明，有较好的参考价值。(Enhance the image of a wavelet method, the process in detail, comparing the results clearly, there is a good reference value.)
