gridtrimesh
通过MATLAB对点云数据生成三维网格,并将三维网格做四边形网格细化处理。其中还有专门生成三维网格点云的MATLAB程序( This example shows how a triangular mesh can be resampled on a
meshgrid -generated square grid. We illustrate the usage of
both functions gridtrimesh and mxgridtrimesh . These two should
produce identical results. Funcion mxgridtrimesh is a compiled
MEX function written in C and should quicker than)

VLC-using-OFDM
将OFDM技术运用在可见光通信的研究，并且把OFDM的高峰均比这一缺点进行了建设性的运用。(In
particular, the use of OFDM (orthogonal frequency division
multiplexing) for intensity modulation is investigated. The high
peak-to-average ratio (PAR) in OFDM is usually considered
a disadvantage in radio frequency transmission systems due
to non-linearities of the power amplifier. It is demonstrated
theoretically and by means of an experimental system that the
high PAR in OFDM can be exploited constructively in visible light
communication to intensity modulate LEDs. It is shown that the
theoretical and the experimental results match very closely, and
that it is possible to cover a distance of up to one meter using a
single LED.)

文章展示了基于高斯混合模型的语音频谱预测方法。频谱预测可能在传包过程中预防丢包这方面起到大作用。期望最大化算法用两倍或三倍的连续语音因素来测试模型。模型被用来设计第一，儿等指令预测量。预测表用频谱分配状态来估计并和一个简单的参考模型对比。最好的预测表得到一个平均频率扭曲值是0.46dB小于参考模型(This paper presents methods for speech spectrum prediction based
on Gaussian mixture models. Spectrum prediction may be useful in a packet transmission system where the sensitivity to packet losses is a major problem.
Models of speech are trained by the Expectation Maximization algorithm using pairs, triples etc. of consecutive cepstral vectors.
The models are used to design first, second etc. order predictors.
The prediction schemes are evaluated using the spectral distortion criterion and compared to a simple reference method. The
best prediction scheme obtains an average spectral distortion that
is 0.46 dB less than for the reference method. )

Signals-and-SystemsAnalysis-and-threalization-of-M
1． 该光盘包含了“信号与系统分析及MATLAB实现”一书的第九章所有程序；
2． 为了方便读者阅读程序，所有程序均采用中文注释。MATLAB的程序编辑器不支持中文显示，用户只需在Word下直接打开源程序文件，即可阅读程序中的中文注释；
3． 程序文件的命名分为以下三种类型：
（1） 若为书中例题的程序，则程序文件名一律以ex开头，后面跟4位数字（前两位表示章号，后两位表示例题序号）表示的该程序所在例题的编号。例如，ex0603.m是例6.3的程序，而ex1102.m则是例11.2的对应程序。
（2） 若为书中图形的实现程序，则程序文件名一律以figure开头，后面跟4位数字（前两位表示章号，后两位表示图形序号）表示的该程序所绘图形的编号。例如，figure1203.m是实现图12.3的程序，而figure0710.m则是实现图7.10的对应程序。
（3） 若为函数文件，则直接以函数名命名，例如文件sconv.m即是书中函数sconv()的对应程序。
