隐马尔科夫模型对文本信息进行抽取利用C＋＋实现(Hidden Markov Model for text information extraction using C realize)

说明：  此程序给出信号的多分辨率分析（Multiresolution Analysis），即信号的多分辨率分解（Multiresolution Decomposition）方法及应用。该程序是一个多抽样率系统（Multirate System）举例，用M个的滤波器，将信号的频谱等分成M部分，使所得抽样频率降为1/M，然后再依据它们的“重要性”给一不同的bit数，那么所传输的bit流必然会进一步下降，起到压缩带宽的作用。(This program gives the signal of the multi-resolution analysis (Multiresolution Analysis), the multi-resolution signal decomposition (Multiresolution Decomposition) method and its application. The program is a multirate rate system (Multirate System) example, with M a filter, the signal' s frequency spectrum is divided into M parts, the proceeds of sampling frequency reduced to 1/M, then according to their &quot importance&quot to the bit of a different number, then the transmitted bit stream is bound to decline further, to play the role of bandwidth compression.)

这是我们参加2011年全国大学生数学建模大赛，做A题的论文和matlab程序，当年获得国奖。 利用此程序可以进行污染源位置反演计算，以及其他类似服从高斯扩散模型的源项反演。 计算量小，简单易懂。(Detect of Pollution source in city.2011 China Undergraduate Mathematical Contest in modeling Q_A.)

用wavedec2()函数对b1,b2两幅图像进行小波分解, 采用’haar’小波, 尝试着分解到第二或第三级 融合两幅图像。(With wavedec2 () function b1, b2 two images using wavelet decomposition, using haar wavelet, trying to break into the second or third grade fusion of two images.)

按照文献《complex networks》中192-193页方法生成的scale free network，有详细注释。此方法有助于理解scale free network的生成原理，并画出了P（k）图，可以自己验证r值是否正确。(According to literature " complex networks" in the 192-193 page method to generate the scale free network, with detailed notes. This approach helps to understand the generation of scale free network theory, and plotted the P (k) diagram, you can verify their r value is correct.)

荷兰瓦格宁根大学研究的温室小气候模型，包含17个状态变化和8个控制变量，具有较高的模拟精度(a complete greenhouse microclimate model developed by wagenigen, have 17 state variables and 8 control inputs,and posses precise simulation error)

使用matlab绘制带有数字标示的等高线(Use matlab draw contour lines marked with numbers)

It provide the implamentation of the graphical user interface for the faces system

此算法用了LMMSE加RLS算法，对接收信号进行仿真，且仿真得到的误码率很小，在工程中也有一定的实际意义。(This algorithm increases with the LMMSE RLS algorithm, the received signal simulation, and the simulated bit error rate is very small, in the project also has some practical significance.)

结合具体例子，通过MATLAB实现通信系统的大部分知识点 (MALTAB and Communication System)
