把信道建模成有噪声的一般离散无记忆信道,并用C语言实现了离散信道容量的迭代算法计算信道容量,利用多个计数器并行传输多位信息等方法提高传输率,采用伪随机序列对发送信息进行扰码的技术增强信道的隐蔽性和抗噪性。
3) non-memory information source
无记忆信源
1.
As corollaries,some Shannon-Mcmillan theorems for arbitrary information source,m-order Markov information source and non-memory information source are obtained and some results for the discrete information source which has been obtained by author are extended.
采用构造相容分布与非负上鞅的方法研究任意信源随机和相对熵密度的强极限定理,并由此得出若干任意信源,m阶马氏信源,无记忆信源的随机Shannon-Mcmillan定理。

采用构造相容分布与非负上鞅的方法研究了m阶马氏信源相对熵密度的强极限定理,由此得出若干马氏信源、无记忆信源的随机Shannon-Mcmillan定理。
5) discrete memory
离散记忆
1.
We show the hysteretic nonlinear behavior of discrete memory,hysteresis loop and “X” shape tangent elastic moduli(Young’s modulus and Poisson’s ratio) in uniaxial cyclic loading experiments,and further clarify it using hysteretic quasi-static stress-strain equation of state in Preisach-Mayergoyz model(PM model) proposed by McCall and Guyer.
HMU中应变的响应与应力的路径有关,模型本身强调了施加于岩石的应力历史在决定岩石的弹性状态时的重要性,因此,可以用来模拟岩石的离散记忆,从这个意义上讲,孔隙饱和岩石的滞后特性是它具有离散记忆特性的原因。
2.
Porous saturated rockshave characters of hysteresis and discrete memory to describe.
引入一种滞后非线性弹性材料的宏观模型——Preisach-Mayergoyz模型(PM模型),该模型是通过大量分散的滞后细观单元的应力对(σ0,σc)对加载与卸载的响应不是原路可逆的特性,导致在循环荷载作用下多孔饱和岩石具有滞后和离散记忆的特征,以此来描述岩石的滞后和离散记忆的。
