Hello!

This is bean, I am studying in Tokyo institute of technology in Japan,

I am trying to make a SISO channel sounder using two USRPN210.

I am facing a problem that PC cannot pick up all the samples from USRP

when I do real-time transmission. In other words, some data are lost
during the transmission.

In order to overcome this problem, I am trying to save one snapshot of

transmit signal into FPGA’s memory at first, then make USRP transmit
this snapshot of signal repeatedly.

In receiver side, I want to make USRP receiver catch one snapshot of
signal, and keep it inside

the FPGA , then I will pick up this snapshot afterwards.

the specification of my channel sounder is like below


center frequency: 2.4GHz

bandwidth: 25MHz


I want to ask about how to save one snapshot of transmit signal into
FPGA’s memory and then transmit it?

also, How can I pick up the snapshot of signal from FPGA?

Can I do this on gnuradio-companion?

or is there any other methods to solve this problem?

Thanks a lot here

Best regards
