说明：  该项目用于通过使用导频序列（训练序列）和信道抽头来估计OFDM中存在的信道。使用BER曲线比较系统的性能，该BER曲线是针对均匀间隔的飞行员和紧密间隔的飞行员获得的。此外，通道抽头的数量也有所不同，以估算最佳的BER曲线
(This project is used to estimate the channel in OFDM by using pilot sequence (training sequence) and channel tap. The BER curve is used to compare the performance of the system, which is obtained for pilots with uniform interval and pilots with tight interval. In addition, the number of channel taps varies to estimate the best BER curve)
