自己编写的用matlab实现概念格的程序，用来求得所有的概念(I have written the concept lattice using matlab procedures used to obtain all of the concepts)

说明：  毕业设计，OFDM系统仿真，并使用多种编解码和纠错码(Graduation Project, OFDM system simulation, and use a variety of codecs and error-correcting codes)

dsb code for understanding it in matlab

最小二乘法的源程序代码,和大家交流下,谢谢指教(Least Squares source code, and the exchange of everyone under the advice Thanks)

说明：  为改进遗传算法的源程序，采用了多次2-opt变异算子，进一步改进了计算结果。(The source code for the improved genetic algorithm using a number of 2-opt mutation operator to further improve the results.)

随机森林论文作者写的随机森林代码，采用matlab混合编程，需要安装Fortran compiler。。。(An interface to the random forest algorithm (version 3.3) written by Leo Breiman and Adele Cutler. This tool is for windows MATLAB R13 only)

北航张志涌的《精通MATLAB7.0》，很详细的介绍了MATLAB的基本命令以及用法，以及SIMULINK的使用方法(Northern Zhang Yong " Mastering MATLAB7.0" , a very detailed introduction to the basic MATLAB commands and usage, and the use of SIMULINK)

现需要在高度为600~700KM范围内，回归周期为30天的太阳同步轨道上布置一颗L波段的合成孔径雷达卫星。 1. 请设计合适的轨道参数，并仿真对应轨道下一个运行周期内星下点轨迹图（纬度和经度两个图）； 2. 计算多普勒中心频率，多普勒调频率与纬度的关系图（设姿态角为0°，天线视角20°~60°，推荐35°）； 3. 按高斯投影方式，将星下点轨迹图投影到地图坐标上。(Now requires a height of 600 ~ 700KM range, return period of 30 days are arranged on a sun-synchronous orbit L-band Synthetic Aperture Radar satellites. 1 Please design the appropriate orbital parameters and simulate the corresponding orbit within the next operating cycle nadir trajectories (latitude and longitude two graphs) 2. Calculate the Doppler center frequency, Doppler frequency and the relationship between latitude Figure (set attitude angle is 0, the antenna angle of 20 to 60, recommended 35) 3 Press Gauss projection, the nadir trajectories projected onto the map coordinates.)

程序采用的是两层循环上实现位移谱的求取。内循环实现在地震波下由上一步所得到的位移、速度和加速度得到下一时间间隔后的位移速度和加速度；外循环实现在不同结构自振周期（频率）下遭遇地震波的响应。(Program uses a two-layer loop on calculate displacement spectra. Cycle based on seismic waves obtained the previous step under the displacement, velocity and acceleration are next after the interval velocity and Acceleration outer loop implementation in different natural period of structure (frequency) the response under earthquake wave.)
