代码说明:

  OFDM信号在无线通信中会受到多普勒频移的影响,从而影响了OFDM信号的正交性,引起载波间的干扰和OFDM信号符号间的干扰,本代码先形成含有N个二进制码元的信号,而这个信号的前半部分和后半部分的信号是一样的,然后根据把这个信号调制成OFDM信号,最后接收端根据这个OFDM信号估计出多普勒因子(OFDM signal in a wireless communication will be subject to Doppler shift of influence, thus affecting the OFDM signal orthogonality, causing interference and interference between the OFDM signal symbol between carriers, the code first formed comprising N binary symbols signal, and the first and second halves of this signal is the same signal, and then the OFDM signal according to the estimated Doppler factor modulates the signal to the OFDM signal received, the last side)

    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.)

    首先用matlab实现了识别算法的仿真,因为只是对特定的数字组合的识别,所以非常的简单,放弃采用比较复杂的识别算法,采用最普通的像素比较的识别算法。(First, to achieve the recognition algorithm using matlab simulation, because the only identification of a specific combination of numbers, it is very simple, give up the use of more complex recognition algorithms compare the most common pixel identification algorithm.)
