calculatin SINR at specific locations of a scene

[KimiaMohsenian]

Dear Sionna Team,

I am working with the “simple street canyon with cars” scene, and I placed two base stations on rooftops and receivers on the cars.
I am moving the cars and would like to calculate the SINR per car per BS. I am using radio maps to show the SINR values at each cell of the scene. But my question is, how can I calculate SINR at exact car locations?

I really appreciate your response.

Hi @KimiaMohsenian,

Please refer to the tutorial https://nvlabs.github.io/sionna/sys/tutorials/HexagonalGrid.html, and especially cell 31, explaining how to compute the post-equalization and per-stream SINR for a specific receiver.

Best regards

Dear @lollodealma
Thank you very much for your help!

Currently, I am working with a very simple setup using the ray tracing module. I load a simple street scene, which is an integrated scene in Sionna, and then I place transmitters on rooftops and receivers on cars. Then I use the "path solver" to get all the propagation paths and calculate CIR between transmitters and receivers.
So I am not doing any pre-coding, equalization, or channel modeling.
Therefore, I am a bit unsure whether I could integrate LMMSEPostEqualizationSINR to calculate SINR per BS per UE for my case. Currently, I am calculating SINR manually using the propagation channel coefficients.

I apologize if my question seems trivial, as I am an absolute beginner with Sionna.

I really appreciate any guidance you could provide!

Best regards
