实现功率谱估计的两种方法，直接法与自相关法(Power spectrum estimation of the two methods, the direct method and the autocorrelation method)

说明：  人脸识别算法PCA的可执行程序，识别率为88.5％，为matlab平台程序，大家共享吧(PCA Face Recognition Algorithm for the executable program, identification rate of 88.5 for matlab platform procedure, let everyone share)

说明：  利用有限单元方法，采用三角形剖分，来求解场值(Finite element method, using triangulation to solve the field value)

　　编写一通用的预测法分析程序，要求有一定的错误处理能力，出错后能够使程序继续运行下去，直到分析过程结束。可通过不同的文法（通过数据表现）进行测试。(Write a generic prediction analysis procedure that requires a certain degree of error-handling capabilities, enabling the program to continue after an error to run it until the end of the analysis process. Can be tested by different grammar (by performance data).)

判断信号质量好坏，主要用于人体生理信号的质量判断(Judgments The signal quality good or bad, mainly used for the the the quality of the judgment of of the the human body physiological signal)

说明：  调频连续波雷达信号仿真，以及信号处理过程仿真，以三角波调制为例，代码编写规范，代码注释优秀。适合初学者以及急需FMCW信号仿真的用户(FMCW radar signal simulation, as well as signal processing simulation, take triangle wave modulation as an example, code writing is standard, code annotation is excellent. Suitable for beginners and users in urgent need of FMCW signal simulation)

PSK调制的原始matlab代码，可以直接使用，打打基础(matlab code for PSK modulation )

This code includes Maximum Variation Methods for Spectral Estimation of SAR Image

设计一个IIR数字低通滤波器， 逼近一组模拟滤波器的指标参数（通带截止频率Wp=2*pi*2000rad/s,阻带边界频率Ws=2*pi*3000rad/s,通带波纹 Rp=3db, 阻带衰减Rs=15db, 采样频率f=10000Hz）； 分别用脉冲响应不变法和双线性变换法实现设计，列出传递函数并描绘模拟和数字滤波器的幅频和相频响应曲线。用上述设计滤波器完成几组给定信号的滤波，证明滤波器的有效性和滤波范围限制.(Design a IIR digital low-pass filter, approaching a group of analog filters indicator parameters (pass-band cut-off frequency Wp = 2* pi* 2000rad/s, stop-band edge frequency Ws = 2* pi* 3000rad/s, pass-band ripple Rp = 3db, stop-band attenuation Rs = 15db, the sampling frequency f = 10000Hz) were used to change the impulse response method and bilinear transformation method for design, list and describe the transfer function of analog and digital filter amplitude-frequency and phase-frequency response curve. A filter was designed with the completion of the above-mentioned groups of a given signal filtering, to prove the effectiveness of filters and filter limit)

这是我一自己编写的 通信系统的 QPSK的基本调制 有需要的朋友看看吧(This is what I have written a communication system for QPSK modulation of the basic right to see a friend in need)
