包含单位负反馈的三阶系统的设计与校正（matlab程序）(Contains the unit)

说明：  这个文件是QPSK的编码文件，利用的是matlab的开发环境，实用的小程序(This file is QPSK encoded file, using the matlab development environment, a small utility program )

通过这个程序可以利用matlab生成word和excel，希望对大家有帮助。(By this procedure can use of matlab generation word and excel, we want to help)

matlab, 对DICOM图像读取，进行阈值运算，改变颜色后输出。(matlab, read DICOM image threshold operation, change colors after output.)

针对强噪声背景中弱信号检测问题，在传统检测方法基础上，提出了基于联合去噪和频率调制的微弱信号检测方法。搭建自相关和小波阈值变换联合去噪系统，极大程度抑制了噪声对检测结果的不利影响。利用频率可调标准信号调制待测信号频率，使得被测信号与检测系统策动力信号的频率差满足检测条件，打破了利用Ｄｕｆｆｉｎｇ 振子检测系统只能检测与系统策动力频率相近信号的限制。(In order to solve the problem of weak signal detection in strong noise background, based on traditional detection methods, puts forward the method of weak signal detection and denoising based on frequency modulation. The self correlation and wavelet threshold transform combined de-noising system can greatly restrain the adverse effect of noise on the detection results. Use adjustable standard signal modulation signal frequency to be measured frequency, the signal detection system and the driving signal frequency difference meet the test conditions, the system can only break detection signal detection and system driving the similar frequency limit by using Duffing oscillator.)
