用于检测信道的训练序列，包括生成过程及信道估计。-Channel for training sequence detection, including the generation process and channel estimation.

实现了OFDM系统在接收端的信道估计和信道均衡的方法，其中考虑了训练序列以及导频的作用-OFDM system is realized at the receiving end of the channel estimation and channel equalization method, wherein the training sequence and considering the effect of the pilot

在超宽带系统中，使用训练序列来进行信道估计，这样可以使得信道估计更加准确。(In ultra wideband systems, channel estimation is performed)

进行帧同步的目的是为了得到帧头的位置，以分辨以符号周期为单位的延时。本质上，目的是寻找一个接收端已知的已发送信号的参考信号（即训练序列）以进行后续的如信道估计和信道均衡的操作。有关帧同步的理论有很多，这里只实现一种基于训练序列的相关性质的方法。(The purpose of frame synchronization is to get the position of the frame header to resolve the delay in symbol periods. In esse

文中在发送数据前先发训练序列和导频序列，在接收端对接收到的信号进行信道估计，再将得到的信道信息来解调我们有用的信号(In this paper, the training sequence and pilot sequence are sent before sending the data, the received signal is estimated at the receiving end, and then the obtained channel information is us
