Simulate MMSE_Receiver_for_DS_SS_in_AWGN_Channel

信号的预处理，去除趋势项，以达到我们所要的信号的形式，效果比较好(Signal pre-processing to remove the trend term, we want to achieve in the form of signals, results were better)

说明：  script for the robot control

Dijkstra s algorithm, conceived by Dutch computer scientist Edsger Dijkstra in 1959, is a graph search algorithm that solves the single-source shortest path

说明：  系统参数辨识，用增广最小二乘算法实现。对书中的程序进行了改进：由于噪声是未知的，虽然我们模拟了系统的随机白噪声，但进行辨识时必须对噪声进行估计，见程序45行和53行。(System parameter identification, with the extended least squares algorithm. Procedures for improving the book: Because the noise is unknown, although we simulate a system of random white noise, but to identify the noise must be estimated, see the program of 45 lines and 53 lines.)

MATLAB 惯导程序 里面有许多有用的程序，自己看吧，不会让你失望的(MATLAB inertial navigation procedures There are many useful program, oneself see, won t let you down )

米字形CFAR，可以处理一些特殊的目标回波，提高检测率，降低虚警(M-shaped CFAR, can handle some special target echo enhance the detection rate and lower false alarm)

Low-pass filter 可自行調整延遲角度(Low-pass filter)

选择13级移位寄存器的初始数据，用移位加反馈的方法生成级数为3~13的m序列(The selection of the initial data of 13 level shift register, series is generated by shift plus feedback method for 3 ~ 13 m sequence )

滤波反投影的CT图像重建算法、人脸识别中核心算法(Filtered back-projection of the CT image reconstruction algorithm, the core algorithm for face recognition)
