Calculating RSS on each receiver antenna element

[rajBakhunchhe]

I have a 4*4 antenna array on receiver. i want to find out received signal strength on each antenna element (or on any specific antenna element), so that I can create a heat-map for the incoming direction of signals (spatial spectrum heatmap) with respect to receiver antenna. So far, I have only been able to find the CIR for each path, but not for each Rx antenna element.
i am a beginner here (as well as in wireless communication) and I would really appreciate your help.

Hi @rajBakhunchhe,
did you already have a look at the RT tutorial?
The CIR is of shape [batch_size, num_rx, num_rx_ant, num_tx, num_tx_ant, max_num_paths, num_time_steps]. You can loop over the num_rx_ant dimension to get the CIRs for each rx antenna element.
I hope this helps.
