现代数字信号处理，自适应谱线增强，求解自相关函数，输入输出信号作比较。(Modern digital signal processing, adaptive line enhancement, solving autocorrelation function, input and output signals for comparison.)

分析了正弦信号分辨率问题，当采样频率相同时，点数越多，分辨率越高，频谱特性误差越小( Analysis the problem of resolution in a sinusoidal signal.When the sampling frequency is the same, the more points,the higher the resolution,and the error spectral characteristic is smaller.)

This is about Digital signal Processing.

以梯度投影法迭代直接求解出观测值的改正数，给出一个简单算例，以资验证。 (The correction of the observation is obtained by the interation with gradient projection method and a simple calculation example is given to verify it)

here is a program MATLAB for maximum smallest, Tiệ m có thể

jpeg matlab program it consist of only discrete cosine transform and quantization

V_RESAMPLE is a Matlab function implementing nonuniform data sampling. It resamples the input data at the specified, continuously variable sampling rate, which may be locally higher or lower w.r.t. the original rate. Aliasing terms are taken care of by appropriate smoothing.

利用线性矩阵不等式编写的可行解求解程序，可以看一下了。(LMI simulation)

用matlab实现的均值滤波函数，可以有3*3,5*5等多种窗口可选(Using matlab to achieve the mean filter function, can have 3* 3,5* 5 and many other window options)

乘法逆元的实现，就是对元素的逆元求解实现(Multiplicative inverse of the implementation of the elements of inverse solution to achieve)
