USRP 2920 Video link with no MIMO cable

[Dor_Afriat]

is there any way to use this example:

without the MIMO cable?

if not, can someone please give me an example to a VI for digital communication link that doesn't require the MIMO cable?

thank you very much.

Hey Dor_Afriat, 

Just for clarity, do you want to just run the example or do you want to run the example with the same results without the MIMO cable?

The MIMO cable is primarily used for synchronizing the USRPs together. If you dont care if the USRPs are out of phase, you don't need the MIMO cable. Or, you can change up the code to synch USRPs together but the rising edge of a clock or something like that. But it really comes down to what do you want to have done.

Hey,

my goal is to prove the efficiency of MRC, so I need the ability to send data from one USRP to two different USRPs, with no MIMO cable between them, and the ability to estimate the channels. the only working example I've found that is able to transmit data between two different USRPs that are not connect is this: https://decibel.ni.com/content/docs/DOC-18801

but the problem with this code is that I don't know how to estimate the channel due to the multiple transmissions. 

thanks.

Could this be helpful? That example looks to have code that does channel estimation. At worst, you may be able to take pieces from both and integrate them together.

thanks for your help, but still- this example requires a MIMO cable.

I have to send data from one USRP to a different USRP that isn't connected to the first one with a MIMO cable, and still be able to receive the data and estimate the channel. Is there any example allowing me to do so? I don't need a complex example, a basic PSK transmitter and receiver would do.

thank you very much.
