DeepMIMO Forum
Hi,
Thanks for your DeepMIMO project! I am currently investigating the possibility to simulate the channel of RIS deployed in indoor environment. Therefore, I considered using the I1 scenario with 1 BS containing 64 (16 * 4 * 1) antennas. However, I have the following two questions:
1. It seems that all 64 antennas can only rotate as a whole, i.e., I cannot rotate two antennas to different angles. Is that TRUE?
2. The output data contains path-loss information, which is great. Is there any reasonable way that I can map the path loss into RSSI (Received Signal Strength Indicator) with the help of your dataset?
Thank you in advance!
- No, this is not true. In the I1 scenario, from the DeepMIMO perspective, every antenna is considered a "separate BS". This means that you can set different rotation parameters to multiple BSs (I1 antennas). To know how, please refer to the "alternative setting (different parameters for multiple BSs)" on the DeepMIMOv2 page.
- Yes, they are inversely proportional. The received power (in dBm) = transmit power (in dBm) + transmit antenna gain (in dBi) + receive antenna gain (in dBi) - path loss (in dB). You just need to choose a certain transmit power value in dBm. The antenna gains depend on the antenna radiation pattern choice and angles of arrival and angles of departure of the line-of-sight path. For the special case of choosing the DeepMIMO option of the isotropic radiation pattern, receive power (in dBm) = transmit power (in dBm) - path loss (in dB).
