对于参数估计问题,克拉美罗界(简称CRB)为任何无偏估计量的方差确定了一个下限. 即不可能求得方差小于下限的无偏估计量,并为比较无偏估计量的性能提供了一个标准. 本程序对CLRB（克拉美罗下界）进行了描述，预留了参数。 希望能对同志们提供帮助。(For the parameter estimation problem, Cramer-Rao bound (referred to as CRB) for any unbiased estimator of variance to determine a lower limit that can not be obtained is less than the minimum variance unbiased estimator and unbiased estimator for comparing the performance of provides a standard procedure for this CLRB (Cramer-Rao lower bound) for a description of the reserved parameters. Hoping to help comrades.)

实现MSK调制过程，通过定义入手，先计算相位，然后分两路调制(modulate msk with noise)

MUSIC程序，用于DOA估计时频估计的程序，MATLAB标准语言，(MUSIC procedures for the DOA estimates of the frequency estimate procedures, standard MATLAB language,)

实现图像的傅里叶高通、低通滤波.经Fourier变换后的图像，中间部分是低频部分，外边是图像的高频部分。经过低通滤波后，图像中的高频成分被滤除掉，只留下低频成分，图像的边缘部分变得比较模糊了(useful for image Fourier high-pass, low pass filter)

这是一个信号处理很好例子，里面三角波，阶跃信号，以及方波信号的处理，有各种变换，同时也有gui方面的参考，代码能作参考，对小白很友好！(This is a good example of signal processing, triangle wave, step signal, and square wave signal processing, there are various transformations, but also GUI reference, code can be used for reference, very friendly to white!)

用matlab求框架的位移，多自由度发，有限元素(Frame------p73 example2.8 Yijun Liu Introduction to FEM & Frequencies calculation)

功率谱估计的各种方法，包括经典法和现代法的matlab实现，不是通过调用函数，而是根据算法的思想实现的，希望对大家有用。(The power spectrum estimation methods, including the classic method and modern method of Matlab implementation, not by calling the function, but according to the idea of ​ ​ the algorithm to achieve, and the hope that useful.)

关于512位的正余弦表，内有两个数组，分别存放已经算好的正余弦数(About 512 positive cosine table with two arrays were stored has been considered a good number of sine and cosine)
