利用matlab实现MSK调制 采用的是CPM调制的调制框图 内附CPM调制框图(MSK modulation implementation using matlab CPM modulated by the modulation block diagram)

3D registration using Matlab

A typical format for a DPPM signal in a UWB system is derived that of a PPM signal. The error probabilities of DPPM with receive diversity over additive white Gaussian noise (AWGN) channels and Nakagami fading channels are analyzed.

常规PID与模糊PID的比较，模糊调节的速度更快。(Comparison between conventional PID and fuzzy PID)

设信号 ，用 对x(t)采样得x(n)，是否会发生频谱混叠？现利用FFT分析其频谱。 1．编程绘制该信号的波形。 2．若令N=16，编程对x(n)做FFT运算，并绘制其幅频特性曲线。 3．令N=1024，编程对x(n)做FFT运算，并绘制其幅频特性曲线。 4．分析2、3的运算结果。 设计调试报告要求： 1．工作原理简述； 2．设计思路； 3．难点及解决方法； 4．设计、调试结果及分析； 5．程序文本及操作步骤。(based signal used to x (t) in the sample x (n), whether there will be a spectrum aliasing? FFT analysis is the use of their spectrum. 1. Programming mapping of the signal waveform. 2. If so N = 16, the programming of x (n) do FFT, and the mapping of its amplitude-frequency characteristic curve. 3. Order N = 1024, the programming of x (n) do FFT, and the mapping of its amplitude-frequency characteristic curve. 4. Analysis of two, three computational results. Design debugging reporting requirements : 1. Principle outlined; 2. Design; 3. Difficulties and solutions; 4. Design, debugging and analysis of results; 5. Text and operating procedures steps.)

很实用的db5小波分解程序，希望对大家有 用(Very practical db5 wavelet decomposition program, hope to have )

利用类处理异常，实现根据异常处理规则，进行异常捕获(The use of unusual types of processing to achieve exception handling in accordance with rules capture abnormal)

按偏差的比例、积分和微分进行控制的调节器简称为PID调节器，是在连续系统中技术最为成熟，应用最为广泛的一种调节器。(According to the proportion of deviation and differential, integral controlling the regulator referred to as PID adjustor, is in continuous system in most mature technique, the most widely used a regulator.)
