| If the channel is not ideal, channel estimation with error effects will induce how much degradation of the proposed system. |
There is no research on non ideal channel state information in this article. If you are interested in this area, please refer to Professor Ding Zhiguo's NOMA-OTFS beamforming optimization design paper. |

| How NOMA technology is reflected？ |
High mobility users use OTFS modulation in the dd domain, which is then converted to the TF domain through ISFFT. Low speed users use OFDM like modulation in the TF domain and achieve NOMA in the TF domain through power control with high-speed users. |

| Do you use rectangular pulses or ideal pulses, considering fractional Doppler？
|
In this article, an ideal pulse shaping waveform is used to ensure the good characteristics of the channel matrix, thereby simplifying the complexity of FD-LE equalization，and this article did not consider fractional Doppler. |
