OFDM

控制行业中重要的least square parameter solution，里面使用了一个例子，可以将输入改变然后使用(control of the most important sectors least square parameter solution , which use an example, we can then use the importation of change)

that is a code for clustering data

adaboost demo this is very much useful to evalute a demo of adaboost

OFDM based sprectum sensing for cognitive radio

Queuing theory it is a simulation for M/M/1 queue and find its state probabilites in steady state for n=5 and find expected delay time

详细介绍混沌序列 对混沌序列编程的指导十分有用 (Detailed introduction to the chaotic sequence of chaotic sequence programming guide very useful)

基于MATLAB的非线性方程二分法求解。(bisection method)

说明：  跳频参数估计论文，通过各种时频分析方法进行处理(Hopping parameter estimation paper, through a variety of time-frequency analysis method for processing)

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.
