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
