BPSK,QPSK等多个调制方式的详细说明及matlab代码(BPSK, QPSK modulation and other detailed instructions and matlab code)

我学习信号系统时原创的用matlab实现的谐波提取 ，两种方案，先分频再提基波，或者利用带通滤波器(I study the signal system to achieve an original harmonic extraction using matlab, the two programs, the first frequency and then Ti Jibo, or the use of band-pass filter )

说明：  EM算法的matlab实现程序，主要用于图象处理(EM)

QAM Modulation of a random sequence after passing a rayleigh channel.

CANDAN 算法历程，通过这个算法可以对正弦信号频率进行精细估计(Quinn algorithm course, you can fine sinusoidal signal frequency estimation by this algorithm)

说明：  分析混沌系统，产生混沌系统的流，很多m文件(Analysis of chaotic systems to generate the flow of chaotic systems, and many m files)

image processing tool box

Sky lab calculate position of satellite in GNSS systems and calculate elevation and azimuth them and show them.

Duffing系统的时域谱图和相空间轨迹绘制，能够帮助初学者很好的理解典型非线性特征(duffing equation Phase plane trajectory)

说明：  hallo this is my program for matlab about segmontation image
