matlab在数学建模中的一些有用例子,希望对大家有所帮助.(matlab in the mathematical modeling of some useful examples, and they hope to be helpful to everyone.)

基于四阶累积量的联合对角化，其中给出两种四阶累积量计算方法，方便理解。这个算法还是比较难的，可以参看下独立分量分析中的jade算法(Fourth-order cumulant-based joint diagonalization, which gives two fourth-order cumulant method, easy to understand. This algorithm is quite difficult, you can see under the jade independent component analysis algorithm)

BPSK匹配滤波器的误码率统计。1.二进制PSK信号进过波形生成器，生成根升余弦信号 2.对信号加噪声 3.接受加噪信号后，匹配滤波 4.统计误码率(BPSK matched filter error rate statistics. 1 signal into a binary PSK waveform generator had to generate root raised cosine signal (2) of the signal plus noise 3. Accept the added noise signal, the matched filter 4. Statistical error rate)

收集了声源定位中的MUSIC算法，包括经典算法，基于解相干的空间平滑算法，修正MUSIC即MMUSIC算法(Collected in MUSIC sound source localization algorithms, including the classic algorithm, based on decoherence spatial smoothing algorithm, modified MUSIC algorithm that MMUSIC)

介绍了一种基于 MA T L A B的多个特定人连接词语音识别的方法，并提出了在进行端点检测时，引入平均的概念能进一 步提高识别率。 此设计是以 L P C C系数、 D T W 算法为核心的基于图形界面的设计。 通过大量的实验测试 ，表明该方法基本达 到屏蔽外界环境的影响 ， 具有非常高的精度识别(: In this paper based on a number of specific persons MA TLAB conjunctions speech recognition method, and presented during endpoint detection, the introduction of the concept of the average recognition rate can be further improved. This design is LPCC coefficients, DTW algorithm as the core design based on graphical interface. Through a large number of experimental tests show that the method is basically to shield the external environment, with very high accuracy recognition)
