系统仿真了HSDPA中的harq系统，对HARQ系统的吞吐量，重传次数做了分析描述 turbo 码matlab编译码程序，包括map和siso译码算法(Simulation of HSDPA in harq system, HARQ throughput of the system, the number of retransmissions to do the analysis described decoding turbo code matlab procedures, including map and siso decoding algorithm)

this source code is zbuildpi matlab

使用马尔科夫蒙特卡洛方法对非常规的概率密度函数进行样本抽取(use MCMC to draw samples)

本软件主要用于结构的时域试验模态分析，包括单输入单输出，单输入多输出和多输入多输出程序设计。传统的模态分析软件大多是基于频域分析方法，需首先对采样信号进行Fourier 变换。本软件使用实测时域信号，无需Fourier变换，可以避免由于信号截断而引起泄露、出现旁瓣、分辨率低等问题对辨识精度的不利影响。此外，节省了计算机运算时间，可以对实际工况状态下的结构进行在线参数识别。(This software is mainly used for the structure of time-domain experimental modal analysis, including single-input single-output, single-input multiple-output and multiple-input multiple-output programming. Traditional modal analysis software are mostly based on frequency domain analysis, needed first sampled signal Fourier transform. The software uses the measured time-domain signal without the need for Fourier transform, avoid truncated because of the signal caused by leaks, there sidelobes and low resolution of the issue of adverse effects on the identification accuracy. In addition, the savings in computing time, to the actual condition of the structure of the state-line parameter identification.)

LMF波形的模糊函数，用matlab编写。(LMF waveform ambiguity function, written with matlab.)

speed control of dc moter using pid controller

是关于雷达系统的代码，主要用于构建基本雷达系统并通过该程序生成的仿真结果进行操作(Code on the radar system, mainly used to build a basic radar system and the simulation results generated by the program to operate)

在matlab开发环境下用k均值算法实现数据的分类，以及得到数据的聚类中心( realizingthe data classification With k-means algorithm)
