Averaging-Filter

用matlab 7.0 编的 主成分分析程序（GUI）(principal component analysis program （matlab7.0 GUI）)

说明：  进行回波积累，我们可以进行相参积累和非相参积累，怎么来实现，还有如何进行比较？(Accumulation of the echo, we can be coherent and non-coherent integration, how to achieve, and how to compare?)

The objective of this project is to design and simulate a single phase half-bridge switched power supply for driving a series of CET coils. The power supply will act like a current source and the switching frequency fs = 1/Ts of the output voltage waveform equals 2.78 MHz.

用于模拟通信系统中不同统计信道场景下的服从不同分布的噪声。(Communication systems used to simulate different scenarios of statistical channel obey different distributions of noise.)

这是一个用matlab编制的绘制风、浪等玫瑰图分布的程序(This is a matlab prepared to draw the wind, waves and other roses distribution program)

求变截面梁的模态，目前只支持一处变截面，可以自己修改尺寸数据，简单好用(mode shape of the stepped cantilever beam)

直流电机的起动，制动，调速。其中含有各个部分的matlab仿真模型。(DC motor starting, braking, speed. Which contains various parts of matlab simulation model.)

Matlab Coce for PCA 4

读取语音信号（用matlab的wavread指令），把语音信号分帧、加窗，进行清浊分割，提取基 频，这一部分较简单，自己编程序做。参考文献自己到图书馆期刊网上查找。 提取语音信号的lpc参数，可调用lpcfit.m 程序（我提供，见附件），将源、目标语音的浊音 段的lpc系数进行DTW规整，调用pathita2.m 程序（我提供，见附件）。将规整得到的lpc系数 转换成lsp参数，调用lpcar2ls.m 程序（我提供，见附件）， 再进行转换映射，调用matlab 的指令newrbe。(read the speech signal (using Matlab wavread Directive), Voice Signal frames, Windowed, Qingzhuo segmentation, extracting fundamental frequency, this part is relatively simple, they programmed to do. References their online journals to the library search. Voice Signal Extraction lpc parameters can be called lpcfit.m (I provide, see Annex), the source, Voiced objective voice of the lpc coefficient DTW structured, Call pathita2.m (I provide, see Annex). Structured to the lpc lsp conversion coefficient parameters, calling lpcar2ls.m (I offer see Annex), the shift mapping, called the directive newrbe Matlab.)
