读入一段数据后，计算有效信号的初至、持时及能量等属性，并作出事件属性判断。(Data into a period of time after the initial calculation of the effective signal to hold the time and energy, such as attributes, and attribute the incident to determine.)

DSP各款芯片的原理图和PCB图，不错的学习资料(DSP sections of the chip and the PCB schematic diagram, a good learning materials)

this is camera interface code for matlab.

说明：  this is matlab pid tuning code

matlab code for simulation of raleigh fading channel.

软件调试方面的书籍，内容不错，而且只有100多页，便于学习，感觉还不错，与大家共同分享。(Software debugging of books, the content is true, and only 100 pages, easy to learn, feel pretty good, and everyone shared.)

BOC信号调制的源码，及BPSK产生信号的源码(BOC signal modulation of the source, and the BPSK signal source generating)

在实际计算中，有时为了避免开方运算，或者要分解的矩阵只是对称而不是正定的，这时可以选用适合于一般对称阵的分解式(In the actual calculation, sometimes in order to avoid root operation, or just want to break down the matrix rather than positive definite symmetric, then you can choose suitable for general symmetric matrix factorization)

首先是针对无或单失效数据情形下，通过多层贝叶斯估计法得到失效概率过后，给出了寿命分布参数的加权最小二乘估计。然后如果失效数据不止一个，使用乘积限估计法来得到失效概率的估计值。(Firstly, the weighted least squares estimation of the life distribution parameters is given by the multi-layer Bayesian estimation method after the failure probability is obtained for the case of no or single failure data. Then if the failure data is more than one, the product limit estimation method is used to obtain the estimated value of the failure probability.)
