MATLAB入门教程的附带程序，适合初学者学习matlab( Fringe code of a MATLAB book .It is fit for beginners to learn matlab.)

对随机信号的功率谱估计，采用多重信号分类进行频率估计(Estimate of the power spectrum of random signals, signal classification using multiple frequency estimation)

This is a DSSS spread spectrum simulation m code, hope to help you a little.

该算法是CHAN定位算法，运用函数的形式编写，利于初学者学校规范化的编程方法(A simple and efficient estimator for hyperbolic location)

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.)

层次分析法！改进的判断矩阵一致性检验 进行矩阵一致性度量的方法主要有两种，一种是由T.L.Saaty提出的一致性比率法C.R.(Consistency Ratio)[13]。还有一种是由Crawford与Williams提出的基于行几何平均法(Row Geometric Mean Method)的几何一致性指标GCI(Geometric Consistency Index)[14]。我们采用的是第一种方法：一致性比率法(C.R.)。(The analytic hierarchy process! Judgment matrix consistency test improved)

Matlab based Wireless card (GPRS/WLAN) driver. or optionally a Bluetooth connection to a GPRS modem

用db4小波分解六层：s=a6+d6+d5+d4+d3+d2+d1(db4 wavelet decomposition of six layers: s = a6+ d6+ d5+ d4+ d3+ d2+ d1)
