satellite visibility

说明：  这是一个很好的用于psk的信道估计算法，包括瑞利衰落信道的估计，并有完整的检测程序。(This is a good channel for psk estimation algorithm, including the Rayleigh fading channel estimates, and a complete testing process.)

for obtaining the period of a signal

signals snr ratio by opertions

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.
