谱相减 ＋ 波束形成 + 后Wiene滤波 语音增强算法(Spectral subtraction+ beamforming+ the Wiene filtering speech enhancement algorithm)

一个简单的四则运算计算器，它能实现两个数据的加减乘除运算，数据需手动输入。因为界面相对简单，方便初学者使用学习(A simple four-function calculator, it can achieve two data arithmetic operations, data to be entered manually. Because the interface is relatively simple and easy to learn for beginners)

说明：  采用MATLAB编写的最新三维数据图形界面，运用GUI编程，输入函数名：volumization (data, n )即可。其中DATA的格式为：[n x m x p]；n表示显示方式： 1 - all, 2 - every second, 3 - every third。 (MATLAB prepared using the latest three-dimensional data graphical interface, the use of GUI programming, enter the function name: volumization (data, n) can be. DATA format in which: [nxmxp] n that display: 1- all, 2- every second, 3- every third.)

一种时频变换方法—伪Margenau-Hil分布，用于信号时频分析。(Of a time-frequency transformation method- Pseudo Margenau-Hil distribution for signal time-frequency analysis.)

新型改进光双二进制传输的编解码方案 提出了改进型光双二进制信号在高速率(≥10Gbit／s)传输时预编码的一种新方案。通过分析编解码过 程，证明该信号传输时不易受码间干扰影响，能用二进制强度调制一直接检测的系统接收信号。仿真产生了该信 号的2种码型。结果表明，采用色散补偿技术能使MD NRZ和MD．RZ信号在长距离传输后克服眼图失真，MD-RZ 信号比MD．NRZ信号在传输后有更低的误码率。(Abstract：Anovel pre-coding schemeformodified optical duobinary signalswasproposed．It couldbe applied to缸ansmit high speed data mte signals(≥ 10Gbit／s)．Through analyzing the process of coding and decoding，It Was demonstrated thatmodified opticalduobinary sign alshave capabilityin reductionofpulse—to-pulseinteraction ， and couldbe di． recaymeasured through aconventionalbinaryintensitymodulationdirectdetection(IM—DD)receiver．Twomodified optical duobinary sign als’formats were simulated to generate．Sim ulation results show that MD．NRZ and MD-RZ signals’ formats Can avoid the eye diagrams’distortion for long—distance transmission，if the dispersion Can be compe nsated in each amplifier span．Moreover,theMD-RZ signalhaslowerBER than theIVID-NRZ signal afterlong-distance comm．unication．)
