本组设计的声音导引系统使用双MCU结构，采用基于时间差的声源定位算法（利用三路接收器的时差信号）结合PID算法判断并控制移动声源的速度。本设计的特色在于使用四阶Butterworth带通滤波器对声音信号进行处理，使其具有较强抗干扰能力。且系统设计性价比高，功耗低。(Our group design the Sound Guidance System based on Bi-MCU configuration, using time difference sound source orientation arithmetic（the time difference signal from three receivers）combining PID arithmetic to determine and control the mobile sound source’s velocity. The feature of the designation is processing the sound signal by four-order Butterworth band-pass filter. This enhances the anti-jamming ability. Furthermore, the system has the high performance and low price.)

产生正交的AM信号和FM信号，信号为复信号，含有I路和Q路，FM信号可设置调制指数变量，运行后可看到仿真时域及其频谱图(Generate quadrature AM signal and FM signal, the signal for the complex signal containing I and Q Road Road, FM signal modulation index variable can be set to run after seeing the time-domain simulation and spectrum)

说明：  OFDM通信系统中的交织编码、解码程序，使用matlab语言(Interleaving OFDM communication system encoding and decoding procedures, the use of matlab language)

PPT_TH发射机：产生uwb信所有的特性参数，仿真发射链路模块的命令行，产生图形(PPT_TH transmitter: generate uwb letter to all the characteristic parameters, the simulation module launch link command line, create graphics)

Code for PPG signal to estimate the HR of subjects doing intense exercises

此程序为matlab的关于空间增强的一段代码，已经用于开发的软件中(This process is enhanced matlab on a piece of code space has been used to develop the software)

说明：  从随机理论中的二项式分布出发。定量分析了伽尔顿板实验，给出了分布函数。(This paper begins with the binomiM distribution in the random theory and then furthers on analysis of the distributive curve of Gahon board experiment)

频谱估计Automatic Spectral Analysis-Matlab code(Accurate estimates of the autocorrelation or power spectrum can be obtained with a parametric model (AR, MA or ARMA). With automatic inference, not only the model parameters but also the model structure are determined from the data. It is assumed that the ARMASA toolbox is present.)
