由matlab实现的HMM，两个文件可以相互参考(Implemented by the matlab HMM, the two files can refer to each other)

学习信道建模的经典教材！尤其是对无线信道建模空时频特性进行仿真的一部重要书籍。(A classic learning textbook about wireless channel modeling!Especially it s an important book for the time-space and frequency characteristics of wireless channel modeling simulation .)

说明：  Edge detection result should be enhanced using linear method like Median filter to remove the garbage around the pupil to gain clear pupil to determine perfect centre. Get the centre of the pupil by counting the number of black pixels (zero value) of each column and row. Then get each row and column that has the maximum number of these black pixels. Then determine the center by simple calculation according to the image coordinate to set it correct on the image, consequently we can determine the radius of the pupil. Thus we can find the pupillary boundary (inner). A similar procedure is extended by using a coarse scale to locate the outer boundary (limbus) which can be apparent by using the mid-point algorithms of circle and ellipse.

产生脉内Frank相位编码调制信号，并对其进行平方、四次方变换，利用四次方FFT结果为单频信号的特点完成调制识别，最后绘图观察其瞬时相位曲线。(Generating pulse code modulation signal within Frank polyphase, and its square, four square transformed by FFT results for the fourth power single-frequency signal modulation characteristics of complete identification, finally drawing to observe the instantaneous phase of the curve.)
