chebyshev statistics calculation of an image

维纳滤波，能滤除干扰噪声，提取有用信号。但是当输入信号的统计特性偏离设计条件，它就不再是最佳的了，这在实际应用中受到了限制。 (Wiener filter, to filter out interference noise, extract the useful signal. However, when the statistical characteristics of the input signal deviates from the design conditions, it is no longer optimal, which has been limited in practical application.)

说明：  一种改进的DE算法，来自文献“JADE: Adaptive Differential Evolution with Optional External Archive”(JADE: Adaptive Differential Evolution with Optional External Archive)

使用matlab编程，实现FFT卷积算法，经过样机的实验，得到正确的结果，而且代码简单易懂。(Using matlab programming, the realization of FFT convolution algorithm, the prototype of the experiment, to obtain accurate results, and easy-to-read code.)

本文的秘密编码离理想的码率还很远，建立的无 条件秘密通信系统的稳定性和秘密性有待进一步证明，无条件安全系统秘密编码 方案还处于起步研究阶段，还有很多新的突破点等待研究。(Stability and secrecy of the secret coding bit rate still far from the ideal, the establishment of the unconditional secret communication system needs to be further proof, the the unconditional security system secret coding scheme is still at an early research stage, there are a lot of new breakthrough wait for research .)

说明：  LDPC 编解码可以在matlab上成功运行(LDPC codec can run successfully in MATLAB)

使用高阶累积量对MPSK信号进行调制识别，效果很好，可以达到很高的识别率，我曾论证了好久，确定它的结果没有问题，确实识别率很高(Modulation recognition of MPSK signals using higher order cumulants good effect, and can achieve a high recognition rate, I have argued for a long time, and its results, is indeed a high recognition rate)
