该系统实现了视频通信系统由通信模块库及使用从视频处理模块块基于MPEG - 1和DVB演示演示基于Simulink模块，它不从源编码，频道编码（RS编，卷积编码器）调制（QAM调制， OFDM）技术，信道及当时的整个过程相反，在接收端 然而，甚少是一个问题，那里的视频源编码器输出去到信道编码，当运行系统，则会出现错误，说的RS -编码器输入不正确，这种输入问题，我想，未来的视频输出 我不会令你对这个问题APRRECIATE＆应该是什么的RS编码器输入的大小帮助？ 原因这是我的硕士论文设计之与我必须完成它正确 任何帮助，您奉献，都可以得益，因此，我感谢您关注..(Received OFDM signal transmitter, using the language toolbox matlab simulink technology)

转矩计算模块，输入包括三相电流ia ib ic，电动势ea eb ec，输出为转矩、转速。(Torque calculation module, the input including the three-phase current ia ib ic, emf ea eb ec, output torque, speed.)

此matab函数文件可以用来计算模型的李雅普诺夫指数，用于稳定性分析。(this Lyapunov.m file can be used to compute the lyapunov exponential)

直方图是用面积表示各组频数的多少，矩形的高度表示每一组的频数或频率，宽度则表示各组的组距，因此其高度与宽度均有意义。 程序提取了很多直方图所需要的参数特征，如均值、方差、偏度、峰度、能量和熵。 (Histogram is that each group size the number of frequency, the height of the rectangular frequency of each group said that the number or frequency, the width of that group from each group, so the significance of height and width of both. Extraction procedures need a lot of parameters histogram features, such as mean, variance, skewness, kurtosis, energy and entropy.)

给定控制顶点，绘制出B样条曲线，不是很好，大家可以学习一下(The given control vertex arrays, fitting out of B spline curve, is not very perfect, we can learn about it )

tA scheme of format conversion optical 16-ary quadrature amplitude modulation (16QAM) toquadrature phase shift keying (QPSK) signal based on cascaded four-wave mixing (FWM) in semiconduc-tor optical amplifiers (SOAs) is proposed. Theoretical analysis and simulations of the format conversionscheme are conducted to validate the feasibility of the proposal. In this proposal, the phase conjugatedof 16QAM signal is generated after the first FWM process in an SOA, and then the QPSK signal is con-verted due to the second non-degenerate FWM (ND-FWM) process in another SOA. The performance andthe optimal design of the 10 Gbit/s format conversion system under various key parameters of SOAs are uated and discussed. Simulation results present useful to enable interconnection between backbonenetwork and access network.
