BPSK的AWGN分析归一化，对初学者会有所帮助(BPSK Analysis of the AWGN normalized, it would be helpful for beginners)

本例演示：如何依靠图形窗 UserData 属性在递归调用中传送用户控件的图柄，保证回调动作正确执行。(demonstration of the cases : how to rely on graphics window UserData attribute in the recursive call to transfer control of the map user handles, callback action to ensure correct implementation.)

包括了LMS算法，RLS算法实现的自适应滤波器，以及Wiener最优滤波器(Including the LMS algorithm, RLS algorithm adaptive filter, and Wiener optimal filter)

计算MSE和PSNR的小程序，自己写的，比较简单实用(MSE and PSNR calculation of small programs, to write their own, relatively simple and practical)

Step 1: Set i=1 FA=f(a) Step 2: while i≤ No do step 3-6. Step 3 set p=(a+b)/2 FP=f(p) Step 4 if FP<TOL or (b-a)/2<TOL then OUTPUT(p) STOP. Step 5 set i=i+1 Step 6 if FA.FP > 0 then set a=p FA=FP else set b=p. Step 7 OUTPUT (‘Method failed after No iteration,No=’, No) STOP.

关于大气MTF的资料，有助于理解大气MTF的作用，估计计算大气MTF的值。(The information on atmospheric MTF, help to understand the role of atmospheric MTF, estimate calculated atmospheric MTF value)

MNIST数据库处理文件，MNIST数据库是由NIST的专用数据库3和包含手写体数字二值图像的专用数据库1组成的。NIST最初指定SD-3作为他们的训练集，SD-1作为他们的测试集.然而，SD-3比SD-1清洁得多，易于识别(MNIST database processing file)
