[srslte-users] Few Questions about srsLTE and BladeRF

[Xavier Arteaga]

Hi Sarp,

1.       How should be my MIMO antenna configuration? This bladeRF has 2 rx
and tx ports.

MIMO operation with srsLTE has not been tested yet.


2.       Is it possible to use 1x1 configuration with this bladeRF?

Yes, you need to install the bladeRF driver from
source https://github.com/Nuand/bladeRF <https://github.com/Nuand/bladeRF>


3.       Do I need amplifier for antennas?

It depends on your eNb location and propagation.


4.       Do I need antenna multiplexor?

Once again, it depends on your setup and propagation conditions.
Personally, I do not use multiplexor. I put the antennas with a 90º angle
between them for reducing Tx/Rx interference.


I hope this helps.
Regards,
Xavier
