Usually, I generate signals by MATLAB and convert it to binary data.
Then, I use “rfnoc_replay_samples_from_file” utility like the following:
./rfnoc_replay_samples_from_file --args
‘type=x300,addr=192.168.20.2,second_addr=192.168.40.2,master_clock_rate=200e6,ignore-cal-file=1’
--freq 2.3e9 --file tx_singleTone.dat --rate 100e6 --ant ‘TX/RX’
As to the OFDM signal, I upconvert the baseband signal to a low IF
frequency by MATLAB, not with the UHD driver.

OK, let's try something simple.
Use the tx_waveforms example to emit a single tone.
Then use the tx_samples_from_file (NOT the RFNOC version)
Are the results different?
