MFCC参数计算，也可进行语音信号处理。 本程序需要调用voicebox工具箱中的melbankm.m程序得到Mel频率滤波器组(MFCC parameters, but also for voice signal processing. This procedure required to call VoiceBox toolbox melbankm.m procedures Mel frequency filter bank)

这是一个比较简单的水箱水位串级控制的程序，供初学者学习。(This is a relatively simple tank level cascade control program for beginners to learn.)

压电陶瓷的经典模型，preisach 模型(piezoelectric, preisach model)

MB-OFDM-UWB系统发射机代码(信号产生/QPSK/OFDM)、802.15.3a信道结构等。(MB-OFDM-UWB system code transmitter (signal generator/QPSK/OFDM), 802.15.3a channel structure.)

二进制通信系统的进行蒙特卡罗仿真程序，以正交信号为基础。当均值分别等于０，０.１，１.０，２．０时完成１００００个比特的仿真并求出误差概率。绘出理论误码率和蒙特拉罗仿真的差错率并进行比较这俩个结果，并绘出每个均值情况下判决器的１０００个接受信噪比抽样(Binary communication systems to carry out Monte-Carlo simulation procedures to orthogonal signal basis. When the mean, respectively, equivalent to 10,000 completed 0,0.1,1.0,2.0 bit error probability simulation and obtained. Mapping theory and蒙特拉罗BER simulation这俩error rate and compare results, and the mean circumstances of each mapped)

说明：  LQR最优控制，可以应用于基于磁流变阻尼器汽车悬架等半主动控制(LQR optimal control can be applied to semi-active control of vehicle suspension based on MR damper.)

Abstract - In this paper, proposed an efficient method of converting speech codec formats between G.723.1 and G.729А. The proposed method is composed of four steps: LSP conversion, pitch conversion, adaptive codebook search and fixed codebook search. Subjective results shown that the proposed method has shorter delay than classical tandem method.
