matlab codes for viterbi encoding

Radio map builder and particle filter for WiFi indoor localisation using the fingerprinting method

盲源分离的FASTICA算法程序，对信号进行分离(Blind source separation procedure of FASTICA algorithm,)

模糊PID的simulink仿真，包含模糊PID的隶属函数，KP，PI，PD的模糊规则(Simulink fuzzy PID simulation, PID fuzzy rules of fuzzy membership functions, KP, PI, PD contains)

说明：  卫星导航与定位中的easy程序：将原始观测数据O-files转换到GPS时间（week+sow）；利用原始观测数据N-files中的时间和星历表计算位置的地心地固坐标；从O-files和N-files获得数据，仅使用伪距，对大于20组的数据进行重复计算，并利用迭代最小二乘法，计算接收机地心地固位置等功能。(Easy program in satellite navigation and positioning: convert the original observation data o-files to GPS time (week + sow); use the time in the original observation data n-files and ephemeris to calculate the geocentric and geocentric coordinates of the location; get the data from o-files and n-files, only use pseudo distance, repeat the calculation of more than 20 groups of data, and use iterative least square method to calculate the receiver geocentric and geocentric Fixed position and other functions.)

数据类型转换,int转换成uint8，比较适用(data change)

三次样条插值法，（Matlab实现）以其中第一类边界条件来实现。(Clamped Cubic Spline interpolation based on Matlab.)

Nonlinear Total Variation based noise removal algorithms. Based on: L. Rudin, S. Osher, E. Fatemi

说明：  用VHDL语言编写的FFT程序，有些参考价值哦(VHDL prepared by the FFT procedure, some reference value oh)
