RFSoC 4x2 Vivado base architecture is great for receiving analog signal, but not for transmitting analog signals. Maybe you could find useful informations in that previous request: [RF SoC 4x2] How to send complexes from a board to another via the analog converters?
Out of curiosity, are you in the ECE department of the IIT? I remember that there was a similar project about transmitting a webcam stream and that GNU radio was used.
