NTN TDL channels detection data

According to the NTN-TDL channel model described in 3GPP TR 38.811, this paper uses MATLAB R2021a for channel simulation and detects four TDL channels using an m-sequence of length 127. After obtaining the output signal, the channel impulse response CIR is obtained by performing correlation operations with the local replica sequence, and the channel frequency response CFR is obtained by performing Fourier transform. Then, feature extraction and data processing are performed to obtain the channel simulation dataset for this paper's experiment.本研究依据3GPP TR 38.811中定义的非地面网络-时延扩展信道（NTN-TDL, Non-Terrestrial Network-Time Delay Line）模型，采用MATLAB R2021a开展信道仿真实验，并利用长度为127的m序列对四组时延扩展信道（TDL, Time Delay Line）进行检测。在获取输出信号后，通过与本地复现序列进行相关运算得到信道冲激响应（CIR, Channel Impulse Response），再经傅里叶变换得到信道频率响应（CFR, Channel Frequency Response）。随后通过特征提取与数据处理，得到本实验所需的信道仿真数据集。
