Wavelet analysis method for knock detection in injection engine

LPCC FUNCTION matlab and signal processing toolbox for the lpc function

用matlab仿真多目标跟踪中的航迹关联融合的程序，相当好啊！！！(Matlab simulation of multi-target tracking with the track association fusion procedure, very good! ! !)

matlab code for multipath rayleigh fading

MATLAB® is a high-level technical computing language and interactive environment for algorithm development, data visualization, data analysis, and numeric computation. Using the MATLAB product, you can solve technical computing problems faster than with traditional programming languages, such as C, C++, and Fortran.You can use MATLAB in a wide range of applications, including signal and image processing, communications, control design, test and measurement, financial modeling and analysis, and computational biology. Add-on toolboxes (collections of special-purpose MATLAB functions, available separately) extend the MATLAB environment to solve particular classes of problems in these application areas.MATLAB provides a number of features for documenting and sharing your work. You can integrate your MATLAB code with other languages and applications, and distribute your MATLAB algorithms and applications.

----------------------------------------------------- This file produces the output file test_impulse.wav containing an approximation to the unit impulse (delta) function. The value of alpha on [0,1] determines the bandlimit of the approximation. This method is used to avoid the technical difficulties in producing (and reproducing) an ideal impulse (delta) function in audio. This file also produces the .wav audio file test_audio.wav which is an audio test vector intended to be used in the impulse response inversion experiment. (4/24/2002) NOTE: Impulse is bandlimited to alpha*Fmax where Fmax = Fs/2, or the Nyquist frequency.

在数字通信系统中，滤波器是其中重要部件之一， 滤波器特性的选择直接影响数字信号的恢复。在数字信号接收中， 滤波器的作用有两个方面，第一是使滤波器输出有用信号成分尽可能强；第二是抑制信号带外噪声，使滤波器输出噪声成分尽可能小，减小噪声对信号判决的影响。 (In digital communication system, the filter is one of the important components of the filter characteristics of the choice of a direct impact on digital signal recovery. In the digital signal receiver, the filter s role is twofold, first is to filter the output useful signal components strong as possible the second is the signal-band noise suppression, so that filter output noise components as small as possible, reducing the noise on the signal the impact of decision.)

这是一个关于盲源分离独立成分分析方法（ICA）的软件包,可用图形界面操作(Here is a blind source separation independent component analysis (ICA) of the package, there are graphic interface operation)

本程序由一对m序列优选对模二加生成一组平衡GOLD序列码，用于对直扩系统仿真之中，通过改变第二个m序列的初始状态可以生成不同的GOLD序列码(This procedure by a pair of m-mode sequence optimization of two-plus-one group to generate a balanced sequence GOLD code, for the DS system simulation, and by changing the second m sequence of the initial state can produce different code sequences GOLD)

程序主要包含幂级数展开逼近余弦及在同一坐标下显示多个曲线。压缩包中还包含相关的参考资料。(Program mainly includes power series expansion approximation cosine and displayed in the same coordinate multiple curves. Compressed package also contains the associated reference materials.)
