Re: [Discuss-gnuradio] Two usrp connected by mimo cable

[Marcus Müller]

Ah sorry ,I misread 2.
So, if you use only one USRP, then there's no frequency offset.

Hi xd,

1. yes
2. yes, unless you have a common 10MHz reference connected to both. That's what the MIMO cable is for.
3. the examples you're looking at.

Thanks so much.

1.Is sbx support the full-duplex?

2.If I use one pc and one usrp to realize the transmit and receive.Does the frequency offset exist?

3.Have some related examples in grc which use one pc to control one usrp to realize the transmit and receive?Have some related examples in grc which use one pc to control two usrp connect by the mimo cable to realize the transmit and receive?

Best regards

Yes you can do that. Also, most daughterboards you can use with the N2x0 are full-duplex capable, so you don't even need to use two USRPs.

Hi:

      Thanks so much.I want to realize the transmit and receive ofdm signal in one pc.Also I want to realize the synchronization.Just combine the tx_ofdm and rx_ofdm grc in one grc and just run?Any suggestion is grateful.Thanks.

Yes. The MIMO cable forwards the data as if it was a network cable and a switch.

Best regards,

Hi all,

         I want to use one pc to control two USRP to send and receive ofdm signals synchronization in the grc.One USRP is used as transmitter and the other one is used as receive.Can it be done by just connect two usrp by mimo cable?

         Thanks in advance.

Best regards,
