SPSS非常好的数学统计软件，里面介绍了SPSS的基本操作，比较实用(Very good mathematical and statistical software SPSS, which describes the basic operation of SPSS, more practical)

说明：  实现汉明码的译码算法 进行正交调制和硬判决 (Hamming code decoding algorithm to achieve the orthogonal modulation and hard decision)

The Haar transform can be expressed in the matrix form as T = HIHT (inverse transform HTTH) where I is an NxN image matrix, H is an NxN transformation matrix and T is the resulting NxN transform. For Haar transform, the transformation matrix H contains the Haar basis functions hk(x). They are defined on a continuous, closed interval, x -[0, 1] for k = 0,1,2 ...,N -1 where N = 2n.( The Haar transform can be expressed in the matrix form as T = HIHT (inverse transform HTTH) where I is an NxN image matrix, H is an NxN transformation matrix and T is the resulting NxN transform.
