NOISE FILTER DEScrition

说明：  matlab的标定工具箱，可以很方便的解决很多问题！很好用的(matlab calibration toolbox, it is convenient to solve many problems! Good used)

说明：  hurst指数估计 This function does dispersional analysis on a data series, then does a Matlab polyfit to a log-log plot to estimate the Hurst exponent of the series. This algorithm is far faster than a full-blown implementation of Hurst s algorithm. I got the idea from a 2000 PhD dissertation by Hendrik J Blok, and I make no guarantees whatsoever about the rigor of this approach or the accuracy of results. Use it at your own risk.

应用sift算子进行图像匹配，效果不错。。。(sift is used to match two picture，the result is good...)

已知一个二维数据，y=f(x), 想使得这个数据绕y轴旋转而成为一个旋转对称的三维数据(A two-dimensional data is known, y=f (x), to make the data around the Y axis and become a rotationally symmetric 3D data)

多目标路径优化问题，模拟退化算法。可以用车辆路径优化(Multi-destination path optimization, simulation degradation algorithm. You can use the VRP)

说明：  根据5G协议要求，产生5G NR下行链路信号，包含各种参考信号形式(According to the requirements of 5g protocol, 5g NR downlink signal is generated, including various reference signal forms)

利用最大值熵法和PSD函数法分别求信号的功率谱密度。(The use of maximum entropy method and the PSD function method for seeking signals in the respective power spectral density.)

集成运算放大电路的实际应用。 适用于高级提升人员(Integrated Operational Amplifier Circuit practical application. Applicable to senior officers for promotion)

一种关于MIMO-OFDM系统盲频率同步的资料文档，用MATLAB进行仿真分析(A novel blind carrier frequency offset (CFO) estimation algorithm was proposed which is based on estimating signal parameter via rotational invariance techniques (ESPRIT) for multi-input multi-output orthogonal frequency division multiplexing (MIMO-OFDM) systems with virtual carriers. )
