SpletLab 3: Frequency-Division Multiplexing Objective: In this laboratory exercise you will investigate sending multiple messages on a single carrier by Frequency-Division Multiplexing (FDM). Each individual message is modulated onto a separate subcarrier then the modulated subcarriers are summed before being sent to the USRP.
