老外写的压缩传感算法（CS），还是不错的，供大家学习(Foreigner writing compressed sensing algorithm (CS), is good for everyone to learn)

一个基于Matlab，simulink的Turbo编码仿真(A simulation based on Matlab, Simulink, Turbo Coding)

使用matlab，绘画出美国的星条旗。请运行main文件(use Matlab, painting the stars and the United States. Please operation main document)

matlab的相空间重构代码，实测能用，是入门的非线性动力系统的好工具。(Good phase space reconstruction code!)

SIMULINK仿真实现BPSK在莱斯衰落+AWGN信道中的调制与解调，并分析了误码率和星座图等等参数。(SIMULINK simulation of BPSK in Rician Fading realize+ AWGN channel modulation and demodulation, and analyzes the bit error rate and constellation parameters and so on.)

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.)

结合短时能量和过零率对一段连续发音的wav文件进行端点检测，将单个词组的发音分割出来。(Combination of short-term energy and zero crossing rate of a continuous sound of the wav file detection, the pronunciation of a single phrase differently.)

用实现的维纳滤波器，三个参数分别是信号源，以及作为样本的信号时间（单位秒）(Wiener filter is implemented using matlab. three parameters are the source, fs, as well as samples of the signal time (in seconds))

通过强大和安全的形象散列 非负矩阵因式分解，在信息取证与安全，376-390，2007年IEEE交易。NMF-NMF-SQ哈希( V. Monga, and M. K. Mihcak, Robust and secure image hashing via non-negative matrix factorizations, IEEE Transactions on Information Forensics and Security, 2(3), 376-390, 2007. NMF-NMF-SQ Hashing)
