软阈值去噪程序。噪声为高斯白噪声，采用软阈值去噪算法可保证信号的能量。(noise)

Calculate the histogram and the entropy of any image. The entropy is calculated using different methods.

说明：  维纳率波器的仿真研究，一个做圆周运动的物体，经观测后有一定的误差和噪声影响，经维纳滤波后轨迹更加清(Wiener rate of wave device simulation, a circular motion of the object to do by observing the error and after some noise by Wiener filtering path is more clear)

MIMO_OFDM的信道估计，方法较多，性能很好，十分完整而强大的程序(MIMO_OFDM channel estimation methods are more good performance, very complete and powerful program)

说明：  本书从MATLAB仿真的角度出发，系统地介绍了系统辨识与自适应控制的基本理论和方法。本书共6章，主要内容为：绪论、系统辨识、模型参考自适应控制、自校正控制（包括广义预测控制）、基于常规控制策略的自校正控制和非线性系统辨识与控制（包括神经网络和模糊控制）。书中每种算法都配有仿真实例、仿真程序、仿真结果以及对仿真结果的简要分析，以便于读者深入理解和运用基本理论和算法(From the perspective of MATLAB simulation, this book systematically introduces the basic theories and methods of system identification and adaptive control. This book has 6 chapters, the main contents are: introduction, system identification, model reference adaptive control, self-tuning control (including generalized predictive control), self-tuning control based on conventional control strategies, and identification and control of nonlinear systems (including neural network) And fuzzy control). Each algorithm in the book is equipped with simulation examples, simulation programs, simulation results, and a brief analysis of the simulation results, so that readers can deeply understand and use basic theories and algorithms.)

宽带信号的空间谱估计以及信噪比等对信号估计的影响，才用聚焦矩阵的方法，采用的聚焦矩阵不同，性能也不同，这里是RSS算法(Spatial spectrum estimation of wideband signals and SNR of the estimated impact on the signal only with the focusing matrix method, using the focusing matrix of different, performance is different, here is the RSS algorithm)
