摘要
给出了一种比较通用的非高斯噪声模型——多模噪声,采用无惯性非线性变换器给出了多模噪声中信号的检测与估计方法,该方法对概率密度函数形状对称的噪声是普遍适用的。在此基础上设计了可用于通信保密的多模噪声,说明了本加密方法适用于无线通信信道加密,并从统计分析的角度研究了可能的密码分析方法。
A more universal model of non - Gaussian noise, multi - modal noise is defined, The inertia - less nonlinear transformer is employed to give out the algorithms of signals detection and estimation in multi - modal noise. The algorithms are applicable to noise with symmetric probability density function. On this base, the multi - modal noise suitable for secure communications is designed. It illuminates that the method is agreeable to channel encryption in radio communication. The potential algorithm of cryptanalysis is studied with statistics.
