扩频通信（DSSS）Matlab仿真程序(Spread Spectrum Communications (DSSS) Matlab simulation program)

Alamoudi in Matlab,this is the advance matlab version.

C-C算法应用关联积分能够同时估计出时间延迟和嵌入维数，是相空间重构的前提。 本程序通过C-C算法计算duffing方程产生的混沌时间序列的时间延迟和嵌入维数。(CC algorithm is used to simultaneously estimate the correlation integral time delay and embedding dimension, is a prerequisite for phase space reconstruction. This procedure CC algorithm duffing equation chaotic time series generated by the time delay and embedding dimension.)

在移动数据通信系统信号经传播媒介到达接收端会发生畸变，现行的通信系统普遍采用 自适应均衡技术来克服ISI和多普勒扩展。自适应均衡技术需要重复发送已知的训练序列直至 有效均衡为止I。“盲均衡(Blind Equalization，BE)111”技术仅利用接收序列本身的相关性便可 均衡信道特性。(Signal in the mobile data communication systems to reach the receiver via the mass media distortion occurs, the existing communication systems are generally adaptive equalization to overcome ISI and Doppler spread. Adaptive equalization techniques need to send a known training sequence repeated until an effective balance date I. " Blind equalization (Blind Equalization, BE) 111" technology is only used to receive serial correlation in itself can be balanced channel characteristics.)

基于spwm调制技术的三电平逆变器Matlab/simulink仿真，做课程设计时使用的。(Based on SPWM modulation technique of three level inverter Matlab/simulink, the do of course design.)

说明：  通过 matlab 编程实现捷联惯导系统初始对准、惯导解算的全过程。 1）初始自对准：利用前10分钟实验车静止的数据进行惯导系统的自对准。采用前2分钟数据进行解析粗对准，后8分钟数据用五状态Kalman滤波器实现精对准；为了验证精对准性能，可在粗对准结果上把航向角人为加一定幅度（如10度）的误差，观察精对准的收敛性能。 2）纯惯导解算：对准结束后转入纯惯性导航解算，要求进行双子样的圆锥和划摇补偿，即每20ms完成一次导航解算，输出完整的导航结果包括三个姿态、两个水平速度和两个水平位置（天向通道发散不必输出），并给出姿态、速度、位置随时间的变化曲线以及位置误差曲线。(The whole process of initial alignment and inertial navigation solution of strapdown inertial navigation system is realized by matlab programming.)
