In this paper, we present a novel data-based method for simultaneous Maximum Likelihood (ML) symbol and carrier-frequency o畇et estimation in Orthogonal frequencydivision multiplexing (OFDM) systems. Statistical properties introduced by the cyclic pre痻, a guard space between OFDM symbols, provide su眂ient information about the unknown parameters. It is shown that the redundancy introduced by this cyclic pre痻 allows the estimation to be performed without additional pilots. Simulations show that the performance of the frequency estimator is applicable in a tracking mode while the timing estimation can be used in an acquisition mode.

改程序从imu中读取数据，计算出载体的轨迹，速度，姿态，并画出速度与欧拉角(this program takes the data from an IMU as the input and calculates the body s trajectory ,velocity and attitude . it plots the velocities and euler angles vs time and the body s trajectory. )

2008最新matlab时频分析中用到的几乎所有函数的源代码及其基本用法。如调幅调频函数及其用法，常用噪声产生函数，尺度变换函数，信号时域和频域处理函数，cohen类双线性时频处理函数用法等等，希望对大家有帮助!(2008, the latest time-frequency analysis matlab used in almost all the function)

自编的神经网络的matlab程序，可以运行哦。(Self matlab neural network program, you can run, oh.)

这个代码的主要作用是练习用的，可以用它来练习，然后得到提高(The code is based on Practice，so we can use it to make some improvement and maybe it can realize some new functions)
