Matlab code for describing linear discriminant analysis

此模块为官网提供，使用MATLAB语言编写，实现傅里叶变换（FFT）功能。(This module is the official website, the use of MATLAB language, realize the Fu Liye transform (FFT) function.)

通过9位置法进行加速度标定，采集旋转数据进行陀螺仪标定以及磁力计的标定，以达到减小误差为后续姿态跟踪或解算提高精度(IMU calibration)

这是基于simulink的ofdm仿真程序， 毕业设计中用的 希望对大家有用(this is a OFDM simulation program based on simulink. and this is also my paper program. i hope that it is benefical to you！it can be used by matlab 2009)

说明：  this is water mark code

A novel multipath matrix algorithm for exact room response identification in stereo echo cancellation.pdf自己编写的这篇英文文献代码(A novel multipath matrix algorithm for exact room response identification in stereo echo cancellation.pdf English literature I have written this code)

预测控制与自抗扰结合的经典文献，可参考学习，有一定启发(Predictive control and ADRC combining classic literature, reference study, a certain inspiration)

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.)

EEOTS algorithm In this paper We merge two unconnected concepts (i) Channel coding can be used to conserve energy by transmitting at reduced power levels over longer durations. (ii) Electro-chemical mechanisms in batteries allow them to recover energy during idle periods. Two kinds of delay constraints were considered, one a deadline constraint and the other an average delay constraint. We achieve an Energy Efficient transmission compared to an other algorithms.
