I have zc706 and FMCOMMS5.

I succeded to run example : Transmit and Receive LTE MIMO Using Analog Devices AD9361/AD9364

but, I want to receive the REAL LTE data in the air.

Can I receive real LTE data?

Thanks a lot.

Hi,

yes you should be able to do this with your FMCOMMS5. You can either look at the code used in the transmit and receive function, modify the centre frequency used and just use the receive code, or you could have a look at the LTE Receiver example.

Regards,

Neil

Thank you, Neil.

I saw the LTE Receiver example, so I modified the centre freq in the code.

so, I can receive some data, but I think it is not successful data.

It seems just noise.. And I got RSRP, RSSI, RSRQ, but

RSRP & RSSI [dBm] are positive number.. it is very weird.

I used FMCOMMS5 with just 2 Antennas.

FMCOMMS5 support 4x4 system. Should I use 4 Antennas to receive?

Or, Should I modify other parameters?

Hi,

This example is only configured to use 1 antenna, so the number of antennas you have connected should not matter. As long as y ou have a good enough signal in range at the frequency you chose, you should be able to decode MIB.

Thanks,

Neil
