srsRAN-MIMO

Setting up a 2x2 MIMO with a 10G Ethernet link. The setup is same as shown in the srsRAN-COTS repository.

To connect the USRP use,

Configure Ethernet Port IP Address

• Set the IP address of the Ethernet port connected to the USRP's port 1:

  • IP Address: 192.168.40.1
  • Netmask: 255.255.255.0

• Verify the connection by pinging the USRP’s default IP address (192.168.40.2):

  ping 192.168.40.2

Detect USRP Device

• Run the following command to identify the connected USRP:

  sudo uhd_find_devices

• This will display details like the model, serial number, and IP configuration.

Probe USRP and Update Firmware

• Probe the USRP to verify connectivity and firmware version:

  sudo uhd_usrp_probe

• If required, update the firmware by following the instructions provided in the console.

Burn Firmware Image

• Use the commands suggested in the console output to burn the appropriate firmware image.
• Wait until the process completes successfully.

Restart USRP

• Power cycle the USRP to ensure the firmware changes are applied.

Verify the Setup

• Confirm the setup by probing the USRP again:

  sudo uhd_usrp_probe

• Check for accurate firmware details and operational status.

Run it with the gNB config given in this repo
