Description: 中心/ 环绕Retinex 算法。自从Retinex 理论提出以来, Land 本人和其他
人先后提出了Retinex 不同的变种, 最新的一个版
本是中心/ 环绕Retinex 7 。该方法比较以前的版
本, 运算速度显著提高, 而且物理意义更加清楚。
这种运算与人类视网膜和大脑皮层神经元的神经生
理学函数相关, 其形式类似于自然视觉科学中常用
来模拟单个神经元感受野的高斯差分函数-center/around Retinex algorithm. Since Retinex theory, Land I and others have raised Retinex different varieties, The latest version is a center/around Retinex 7. The method compared with the old version, computational speed significantly improved, but more clear physical meaning. Such operations and human retinal neurons in the brain and nerve function related physiology, form similar to the natural visual science used to simulate the feeling of individual neurons in the wild Difference of Gaussian function

Description: 里面有8PSK，GMSK的matlab源程序，贡献出来了-I was interested in the theory for 8PSK and came across this m-file written in 1999. It
requires 2 function calls (graymapPSK and grayunmapPSK) which I have
included and must be uncommented(single comments only) and loaded into your workspace.
Remove the function calls from this m-file after you load into your
workspace.
It seems to work well and give valid results for BPSK and QPSK but I have a question
about the setup for 8PSK and the solution for Pseint where Pse=Pseint.
Also, the Gray coding seems different than what I m used to.
Some of you more theoretical minded may have some insight into the theory
behind how Pseint was determined and comment. I don t have the
communications toolbox-blockset and was wondering how it compared with Matlab s
example simulation of 8PSK with Gray coding (in Simulink?)
Each run takes about a minute and the loop iterations are shown in the
command window.
A numerical example of a satellite link is shown using uncoded QPSK

Description: Function to plot the Region of convergence for Suprathreshold stochastic resonance+Translation invariant wavelet packet transform detector for transient signals. Hypotheses:
Ho : x[n] = w[n] i.e. signal absent
H1 : x[n] = s[n] + w[n] i.e. signal present
NOTE :
received1 IS A CELL ARRAY corresponding to signal + noise.
received2 is a CELL ARRAY corresponding to the noise alone.-Function to plot the Region of convergence for Suprathreshold stochastic resonance+Translation invariant wavelet packet transform detector for transient signals. Hypotheses:
