We have used Matlab to generate *.mat file, a file around 1966240 complex number OFDM samples.
Thinking to (I) transmit between two USRPs, (II) let the receiver side saving data into file, and later (III) putting the file on Matlab for demodulation.
1. What is the best way to do it? like create GRC blocks? or UHD example?
2. How can I make sure that the TX part will stop when those 1966240 samples are sent. and RX part will stop when completely receiving those 1966240 samples?
3. Should the file type be the *.dat?
