denoise
In BayesShrink[5] we determine the threshold for
each subband assuming a Generalized Gaussian
Distribution(GGD) . The GGD is given by
GG¾ X ¯ (x) = C(¾ X ¯ )exp¡ [® (¾ X ¯ )jxj]¯ (6)
¡ 1 < x < 1 ¯ > 0, where
® (¾ X ¯ ) = ¾ ¡ 1
X [ ¡ (3=¯ )
¡ (1=¯ ) ]1=2
and
C(¾ X ¯ ) = ¯ ¢ ® (¾ X ¯ )
2¡ ( 1
¯ )
and ¡ (t) =
R1
0 e¡ uut¡ 1du.
The parameter ¾ X is the standard deviation and ¯
is the shape parameter It has been observed[5] that
with a shape parameter ¯ ranging from 0.5 to 1, we
can describe the the distribution of coefficients in a
subband for a large set of natural images.Assuming
such a distribution for the wavelet coefficients, we empirically
estimate ¯ and ¾ X for each subband and try
to find the threshold T which minimizes the Bayesian
Risk, i.e, the expected value of the mean square error.

HDB3decoding
数字基带信号的传输是数字通信系统的重要组成部分。在数字通信中,有些场合可不经过载波调制和解调过程,而对基带信号进行直接传输。HDB3码的作用是对数字基带信号进行编码,便于在接收端对定时分量的提取。(Digital baseband signal transmission is an important part of digital communication system. In digital communication, some occasions without carrier modulation and demodulation process, and to direct transmission baseband signal. HDB3 code is used to encode digital baseband signal, facilitate at the receiving end of timing component extraction.
