Image_Restoration

This Matlab source code is for paper DEEC for wireless sensor networks.

说明：  用MATLAB语言编写的基2 DIT FFT子程序& 用简单的速度很低的方法计算DFT(using MATLAB prepared by the two-DIT FFT routines)

用matlab对一张图片进行DFT变换，DCT变换,比较保留20个DCT变换系数重构的图象与原始图像的差别.(Using matlab on a picture to DFT transform, DCT transform, compared to 20 DCT transform coefficients to retain the image reconstruction of the difference between the original image.)

实现声音信号倍频程和1/3倍频程的计算，并附有A计权修正的功能(Achieve voice signal octave and 1/3 octave calculations, along with A-weighted correction function)

对萨德系统AN/TPY-2雷达的威力范围进行仿真计算。原创！！(The power range of SAD AN/TPY-2 radar is simulated. Original!!)

模拟退火算法训练程序，结合了BP神经网络算法(The simulated annealing algorithm for the training program, combined with the BP neural network algorithm)

说明：  可以实现matlab对16QAM和64QAM的星座图实现并进行误码率比较(Matlab can realize the constellation of 16QAM and 64QAM and compare the bit error rate)

程序设计问题和学习有效题目，可以有效提高初学者学习能力。(it can inprove the ability of the learners)

一个很好混沌系统的程序,是离散混沌系统(a good chaotic system procedures, discrete chaotic system)
