I have some question about involving fast fading when calculating SINR of UE.
1. What do these three parameters (i.e., zeta,chi,psi) mean?
[zeta,chi,psi] = obj.downlink_channel.fast_fading_model.generate_fast_fading_signal(t,tx_mode);
This is line 371 of UE.m
2. What does theta mean?
theta = obj.downlink_channel.fast_fading_model.generate_fast_fading_interference(t,tx_mode,interfering_eNodeB_ids);
This is line 407 of UE.m
3. In general, I am quite confused about involving fast fading when calculating SINR, especially with MIMO setting (e.g. TxD, Spatial Multiplexing). Could you please recommend corresponding learning materials or papers, in order to understand the matlab code better? Thanks.
