I found a video on Youtube where a person transfers messages from one USRP to another using Packet Encoder and Packet Decoder blocks. I can reproduce most of the scheme, but these blocks are not used in Gnu Radio right now. As there are alternatives to replace Packet Encoder and Packet Decoder to get the same result.
At the moment I am trying to transmit data using QPSK modulation. But as I understand it, in order for me to get the desired result, I need a packet data transfer. So I need help about replacing the Packet Encoder and Packet Decoder blocks. QPSK scheme
