this matlab code for LS and MMSE channel estimation

本程序的功能是：实现惯性导航参数的自标定过程。(Realize the self-calibration process of inertial navigation)

FAST FOURIER TRANSFORM ALGORITHM To compute the coefficients in the discrete approximation

程序实现了直接序列扩频通信系统，简单易懂。(Program realization of the direct sequence spread spectrum communication system, straightforward.)

通过此程序可以对通过建立偏最小二乘法和互信息偏最小二乘法两种模型来预测燃油品质，并对两种方法进行比较(This procedure can be through the establishment of mutual information and partial least squares PLS two models to predict fuel quality, and compare the two methods)

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.)

蝙蝠算法( BA) 是 Yang 教授于 2010 年基于群体智能提出的启发式搜索算法,是一种搜索全局最优解的有效方法。该算法是一种基于迭代的优化技术,初始化为一组随机解,然后 通过迭代搜寻最优解,且在最优解周围通过随机飞行产生局部新解,加强了局部搜索。与其他算法相比,BA 在准确性和有效性方面远优于其他算法,且没有许多参数要进行调整。
