用R/S估算法计算时间序列的HURST指数(With R/S method to estimate time series HURST index)

生成FPGA编程中rom初始化需要的.mif文件。生成的为1个周期方波波数据。宽度为8，深度为1024(Generate FPGA programming rom initialization required. Mif file. Generated for a cycle square wave data. Width is 8, a depth of 1024)

一个报童从报刊发行中心订报后零售，每卖一份报纸可赚钱a元；若报纸卖不出去，则退回发行处，每退一份要赔钱b元。每天报童卖出的份数是随机的，但报童可以根据以往卖报情况统计得到每天卖k份报纸的概率密度p(k)。 （1） 求报童每天期望收益达到最大（或损失达到最小）的定报量z。 （2） 改变参数a/b的值，观察订报量的最优值变化，画出变化曲线。 试画出仿真流程图，进行程序实现，并对仿真结果进行分析。 (A newsboy subscribe from the press after the retail distribution centers, each sale of a newspaper can make money a million if newspapers can not be sold, then returned to Issue Department, each retire to a loss of a b element. Newsboy sold shares in a day is random, but the newsboy can sell based on past statistics reported to be selling daily newspaper k the probability density p (k). (1) seeking newsboy expected profit per day to maximize (or minimize loss) reported that the volume of fixed-z. (2) change the parameters a/b values, subscribe to observe changes in the volume of the optimal value, draw curve. Simulation test to draw a flow chart for program realization, and simulation results for analysis.)

OFDM 仿真程序，包括编码、调制,IFFT等。(OFDM simulation program,including coding,modulation and IFFT.)

matlab学习刚起步，可以进步很快，大家一起学习一下(Matlab is a very useful software, we study together)

小波变换算法，用于多种信号处理，C++编写，非常有用(wavelet transform algorithm used in a variety of signal processing, C prepared very useful)

费诺码在MATLAB条件下的实现，可按概率降序排列的码字，求出码长及编码时间等功能(Fenno code in MATLAB to achieve under the conditions, in descending order according to the probability of code word obtained code length and coding time and other functions)

阀控液压马达力控系统模型，实现扭矩控制,液压阀为伺服阀(valve control hydralic motor of T_control)

主要是matla中的snake算法的一些模板套路，像是snakedeform、snakedisp、gaussianMask等(The snake is mainly matla some templates algorithm routines, such snakedeform, snakedisp, gaussianMask etc.)
