1. There is a file source that frames data packets for the test_demo. This is part of a transmitter USRP. 2. I have another USRP as receiver that sends an ACK upon reception of data packets to the transmitter. 3. Start sign is a threshold value. If the packet information (calculated by some method) exceeds this threshold, transmission starts and upon receiving an ACK stops. 4. I change this threshold value for every new iteration and count how many packets were transmitted before receiving a success ACK. I can do this manually for every iteration but how to automate it for say some 1000 iterations?
I hope it explains everything.
