Key Takeaways

- Different forms of OFDM, including windowed and filtered OFDM, offer variations of the standard OFDM system.
- The 5th generation waveform, 5G NR, uses variable subcarrier bandwidth or adaptive subcarrier bandwidth.
- Different architectures of realizations and the gains associated with them are crucial in 5G technology.
- Filter bank multi-carrier communication systems can be designed to ensure no Inter Symbol Interference (ISI) and Inter Carrier Interference (ICI).
