Hello Ilgaz,
Please note that in typical wireless communication systems, “Line-Of-Sight” (LOS) conditions often result in better signal propagation characteristics compared to “Non-Line-Of-Sight” (NLOS) conditions. NLOS conditions can lead to higher path loss, multipath fading, and increased likelihood of obstructions, which can degrade signal quality and increase estimation errors for tasks such as “User Equipment” (UE) position estimation.
To troubleshoot this issue, you can refer following steps:
- Review the path loss model and ensure it differentiates between LOS and NLOS conditions.
- Verify that the LOS array is correctly used in the path loss calculations.
- Examine the position estimation algorithm to see if it accounts for propagation conditions.
- Check for any compensating mechanisms or error sources that could be overshadowing the LOS/NLOS effects.
- Run separate, controlled simulations or consult the documentation for the model to understand how LOS/NLOS conditions are expected to impact the results.
