Problem in CIR.ipynb

When I try to run CIR.ipynb in jupyter notebook using the address of the backend http://omniverse-server:8888/, I meet the following problem:

IndexError Traceback (most recent call last)
Cell In[10], line 41
37 buffer_rx_delay = buffer_tx_delay.get(rx_id,np.zeros((n_taps, n_rx_h * n_rx_v * n_rx_p, n_tx_h * n_tx_v * n_tx_p), dtype=float))
39 for tau in np.arange(0,len(cir_delay)):
—> 41 buffer_rx[tau,rx_cm_idx, tx_cm_idx] = complex(cir_re[tau], cir_im[tau])
42 buffer_rx_delay[tau,rx_cm_idx, tx_cm_idx] = cir_delay[tau]
44 buffer_tx[rx_id] = buffer_rx

IndexError: index 500 is out of bounds for axis 0 with size 500

Before runnning CIR.ipynb, I perform the following steps

  1. I follow the steps in the “Installation->validation” to create the data.
  2. I successfully run CFR.ipynb in the jupyter notebook.

Furthermore, no other changes are made.

Could anyone give me some help?

Hi @wj_zhou
How many RUs and UEs are there in your scene? and how long are you running the simulation for?

Hi @wj_zhou
Please try the following to resolve the issue:
In CIR.ipynb cell #10 add:
MAX_PATHS=1024
and then replace “n_taps” with “MAX_PATHS” in buffer_rx and buffer_rx_delay assignments.

There is one RU and one UE. The duration is 10s.

Thank you for your help. I solve the problem.
