卷积码是一种有记忆的编码,在任意给定的时间单元处,编码器的n个输出不仅与此时间单元的k个输入有关,而且也与前m个输入有关。卷积码通常表示为:(n,k,m)
本次仿真采用(2,1,3)卷积码。
(convolutional code is a kind of code memory, in any given unit of time, the encoder output n this time not only with the elements of the k input, but also with the input m. Convolutional codes are usually stated as : (n, k, m), the simulation used (2,1,3) convolutional code.)

MFP_based_on_High_order_Statistics-master
浅层海洋环境由信源组成声源,海洋形成信道,和水听器阵列组成接收器。在这个传播模型中,信源,信道和接收信号这三者,通常能知二求一,具体应用诸如利用海洋环境参数和接收到的信号来定位声源,或者通过计算发射信号和接收信号之间的差异,反演海洋环境参数。
而在接收器方面,我们通过设置各向同性的水听器阵列。通过算法和处理器,我们便能量化模型,传统是处理器主要基于接收信号是高斯信号,而海洋中存在着大量的有色噪声。本课题的研究目的便是在前人的基础上,在海洋声层析成像的背景下,在信源与接收器阵列之间,引入信号的高阶统计量,对非高斯过程的水下信号源进行定位,并提高算法的性能和准确性。
利用非高斯过程的高阶累积量不恒为零的特点,滤去高斯有色噪声对信号的影响,其又包含了信号的相位信息,便可以极大的优化匹配场处理过程的性能和准确性。(After receiving signals based on high order cumulant matched field processor after matched field localization, the positioning effect will be more accurate, sidelobe suppression more effectively, and compared with other traditional matched field processor in low SNR environment, it can position more accurately.)

相信大家已经注意到了,伴随着微观金融理论的发展,以随机分析为核心的数学理论
也在同步发展,并不断为金融学家们所吸收和运用,它们交织在一起,密不可分又相映生
辉②。它们相映生辉倒不要紧,但就给研究者带来了很多困难:由于微观金融学研究重点的
特殊性和复杂性(不确定性和动态性),注定以随机分析作为其主要数学工具,这无形中提
高了这一学科的门槛③。

Logos
说明
在此分类的PRJ我们试图通过分配给每个签名的两个不同的公司标识由一个特别号码提取水平和垂直扫描每幅图像矩阵。每个标志图片被截断成二进制后调整大小。这是由核心例行imcount.m,而主编testpng.m运行compelte测试结果显示出来。每个标识的痕迹便可以进一步处理像一个合适的神经网络学习,推理机等熵类分类指数使用的系统是更好的有关报告,从http://cag.dat下载的解释。 demokritos.gr/publications/TR2011-1.pdf。
该例程index0.m提取每个图像矩阵的行/列聚类分析,现在可以用来替换为最新版本的“cluster.m“另一包“DEC2NARY“我们Mathworks公司提供的帐户中。
MATLAB的MATLAB的版本7.4(R2007a)(Description
In this prj we attempt to classify a number of Company Logos by assigning to each 2 distinct signatures extracted by a special horizontal and vertical scan of each image matrix. Each Logo picture is truncated to binary after resizing. This is done by the core routine imcount.m, while the main prog testpng.m runs a compelte test and displays results. Traces of each Logo could then be further processed by an appropriate learning system like a Neural Net, an Inference Engine, etc. The entropic-like index used for classification is better explained in the associated report downloadable from http://cag.dat.demokritos.gr/publications/TR2011-1.pdf.
The routine index0.m used for extracting the cluster analysis of each image matrix row/col can now be replaced by a most recent version "cluster.m", contained in another package "DEC2NARY" available by our Mathworks account.

LZ复杂度反映的是一个时间序列中,模式数量序列长度增加的速率。为了在计算机上对连续信号的复杂度进行计算,需要先将连续信号离散化,通过预处理后的心音信号符合这个要求。实现心音信号的分离(LZ complexity reflects a time series model number sequence length to increase the rate. For a continuous signal on the computer, the complexity of the calculation, you need to first discretize the continuous signal by pretreatment of the heart sound signals meet this requirement. To achieve the separation of heart sound signals)
