随机信号分析实验随机信号分析实验随机信号分析实验随机信号分析实验 一一一一、、、、实验目的实验目的实验目的实验目的：：：： ⑴ 了解随机信号自身的特性，包括均值（数学期望）、均方值、方差、相关函数、概率密度、实验原理实验原理实验原理实验原理： 我们把除了白噪声之外的所有噪声都称为有色噪声。就像白光一样，除了白光就是有色光。 (Experimentelle Analyse von zufä lligen Signal Analyse der zufä lligen Signal Analyse der experimentellen zufä lliges Signal Analyse der experimentellen Test 1111 zufä lliges Signal,,,, Labor-experimentelle Zwecke im Sinne der experimentellen Zwecken Zweck des Experiments:::: ⑴ zufä lliges Signal über ihre Eigenschaften, einschließ lich Mittelwert (mathematische Erwartung) , quadratische Mittelwert, Varianz, Korrelationsfunktion, Wahrscheinlichkeitsdichte, die experimentelle Prinzip Prinzip Prinzip Experiment Experiment Experiment arbeitet: Neben dem weiß en Rauschen, als wir alle werden als farbiges Rauschen bezeichnet, Lä rm. Wie Weiß , mit Ausnahme der weiß en ist ein Schatten.)

Turbo decoder under awgn channel. (The input is: uncoded bits,coded bits 1,coded bits2(interleaved), LLR from other source(if use only one turbo code ,fill all zero is ok), numbers of iterations, interleaver between two CC, source bit,decoder id(if used in parreled connected turbo codes), interleaver between two sources(under the situation of two turbo codes).)

运用MATLAB编程实现歌曲“最炫名族风”节奏的产生。(Using MATLAB programming song " most unusual family name wind" rhythm generation.)

matlab环境下数学建模中参数估计的问题及所有源程序(matlab environment, mathematical modeling and parameter estimation problem of all the source code)

Moment Invariant source code in matlab

CO-KRIGING WITH RANDOM METHOD. 随机结合克里金方法。在地学中有很大的应用潜力，比如建模及矿物分布估计。(a variant of cokriging, in which the mean values of the vector components are related by linear combinations with known coefficients. Equations for the cokriging predictor and for the variance–covariance matrix of prediction errors are presented. A set of computer programs is provided and illustrated with applications to mineral resources evaluation, in which the proposed cokriging variant compares favorably with traditional approaches.)
