1. The problem statement, all variables and given/known data I want to simulate OFDM using 16-bit QAM in Simulink. The main problem that I'm facing is regarding generation of digital signals and splitting a digital signal into two or more data streams, as we require in OFDM. 2. Relevant equations 3. The attempt at a solution I have tried my bit. I have been able to simulate Analog signals, but digital signals are proving problematic for me.
