用LSM算法来反演雷达海杂波图像，获得海浪的各种特征信息(LSM algorithm used to invert radar sea clutter images, access information about various features of the waves)

這是一個利用butter filter 的bandstop 來濾除原始訊號中有雜訊的方法，先轉為spectrogram觀察雜訊所分步頻帶與能量，再依照要濾除的部分作bandstopa(This is a use of bandstop butter filter to filter out the noise of the original signal has a method, the first step into a spectrogram observation noise and energy of the band, then follow to filter out parts for bandstopa)

图像的二值化,不使用Matlab自带的语句处理，使用的是自己的编程语句。(Binary image, do not use Matlab s own statement processing, using their own programming statements.)

数字图像处理之差影法源程序（初学者必备）(Digital image processing of subtraction method source (beginners necessary))

低通和高通滤波程序，是常用的图像预处理程序(lowpass filter program and highpass filter program)

M序列发生器函数，使用m文件实现，2至7级寄存器，主要分为两个部分。第一部分主要负责输入，输出，第二部分是M序列发生函数(M sequence generator function, 2-7 registers, divided into two parts. The first part is mainly responsible for the input, output, and the second part is the sequence generating function M)

acdc_sym: appoximate joint diagonalization (in the direct Least-Squares sense) of a set of symmetric matrices, using the iterative AC-DC algorithm.

LTE系统中CQI的映射列表，从中可以查出系统工作过程中对应的CQI情况(CQI mapping list LTE system, which the system can find out the work process corresponding CQI case)
