simulink仿真教程，蹦极模型建模和仿真，传递函数，状态模型(simulink simulation tutorial, bungee modeling and simulation, transfer function, state model)

极力推荐，PKU-Matlab课程的学习的PPT，很适合初学者。(Highly recommended, PKU-Matlab courses of study on the PPT, it is suitable for beginners.)

主要用于对含有噪声的信号进行降噪处理，先小波包降噪再奇异值降噪(It is mainly used to denoise the signal containing noise. First, the wavelet packet de-noising and then the singular value denoising)

中频70M，30M带宽LFM信号，采样率为102.4M，数字下变频后，还进行了三倍抽取，最后还得到I，Q两路信号 (IF 70M, 30M bandwidth LFM signal, the sampling rate of 102.4M, digital down conversion, the samples were carried out three times, the last also I, Q two-way signal)

对一段语音信号进行预处理，加窗，求过零率，短时能量，求各种语音信号的特征参数。(For a period of speech signal pre-processing, windowing, and zero-crossing rate, short-time energy, and all kinds of speech feature parameters.)

05年美赛O奖论文的程序和说明，在原作者的基础上有所改进(2005 US-race procedures and instructions for O Award papers, an improvement on the basis of the original author)

应用小区域方差对比，程序简单，本程序的性能已经达到较高水平，阵列信号处理的高分辨率估计，现代信号处理中谱估计在matlab中的使用，主要是基于mtlab的程序，关于小波的matlab复合分析。( Application of small area variance comparison, simple procedures, The performance of the program has reached a high level, High-resolution array signal processing estimates, Modern signal processing used in the spectral estimation in matlab, Mainly based on the mtlab procedures, Matlab wavelet analysis on complex.)

这是一种十分常见的简单的MINO阐述的新方法的MATLB代码，基于这种方法可以极大的减少误码率和码间干扰。(This is a Matlab code of a very popular and simple transmit method based on MINO system. By using it, the BER can be greatly redused.)

This report explains the queuing systems in a small clinic which has two types of queuing systems and can be denoted by Kendall’s notation M/U/1 and M/M/2. The confidence intervals for necessary queuing parameters are calculated for both of the queuing system. Finally in the view of the results the critical issues are discussed.
