[srslte-users] Channel estimations in LTE setup

[Student shrf]

Dear SRS Community,

I am working on TDD-LTE open sources, using srs at UE side and OAI at enb.
I am inspecting the channel estimations obtained at both sides, wondering
whether they have the so-called ``reciprocity’’ property we theoretically
expect in TDD connections, or not. Specifically, I am examining ul_ch_estimates
as the channel estimates at eNB side and ue_dl.chest_res.ce as the channel
estimates at UE, while I get a maximum (normalized) cross-correlation of
0.4.

An image of the deployed setup is attached to this email.


I appreciate the community letting me know if anyone has had a similar
observation on channel estimations.

Thanks,

Mehdi
