用汉明窗作的语音去噪低通滤波器，matlab程序（自己做的，复制到.m文件，完全可运行）(Hamming window used for speech denoising low-pass filter, matlab program (their own, and copied to. M documents, completely run))

用matlab编的gauss算法,希望多大家有帮助(Matlab code for gauss algorithm with)

本论文首先阐述了利用Duffing振子进行微弱信号检测的基本方法及具体实现方法，论证了根据系统相轨迹的变化来判断目标信号中是否含有周期信号的混沌振子检测方法。将Lyapunov特性指数作为一种定量的混沌判别方法应用到微弱信号混沌检测领域，分别研究了连续系统和时间序列的Lyapunov指数计算方法。(his paper first discusses how to use the Duffing oscillator are the weak signal detection, the basic method and the realization methods, proved according to the change of the phase track system to judge whether a cycle of target signal of chaotic oscillator signal detection methods. Will Lyapunov characteristics as a quantitative index of chaotic identifying method applied to a weak signal detection field chaos, respectively, the continuous system and research of time sequence Lyapunov index calculation method. )

猜数游戏，课表排序等matlab程序，兴趣和实践同时培养(to make a ridle game or to make a good plan to study)

关于基音周期的提取，倒谱法的改进，利用预测余量(On the pitch period extraction, improved cepstrum method, the use of margin forecast)

说明：  在MATLAB中编写程序，利用三边定位算法对未知节点定位。已知在平面坐标系内，三个锚节点的坐标分别为(50,100)、(0,0)和(100,0)，在0≤x≤100，0≤y≤100的区域内随机产生10个未知位置的节点（其横、纵坐标均为上述范围内的随机数）。 利用三边定位算法 对这10个未知位置的节点进行定位（计算其坐标值），并与其真实位置（随机产生的坐标值）进行比较(MATLAB three-side positioning algorithm)

数字频率调制又称频移键控（FSK），二进制频移键控记作2FSK。数字频移键控是用载波的频率来传送数字消息，即用所传送的数字消息控制载波的频率。2FSK信号便是符号“1”对应于载频，而符号“0”对应于载频（与不同的另一载频）的已调波形，而且与之间的改变是瞬间完成的。 (Digital frequency modulation called frequency shift keying (FSK), binary frequency shift keying recorded as 2FSK. Digital frequency-shift keying is the carrier frequency to transmit digital information, that is, the number of messages transmitted with the control of the carrier frequency. 2FSK signal is the symbol of "1" corresponds to the carrier frequency, while the symbol "0" corresponds to the carrier frequency (with a different carrier frequency to another) and modulated waveform, but also between the change was instantaneous.)
