Waveforms Beyond 5G - Part I — Lesson 1

This lesson explores the waveforms that have been contenders for 5G, their backward compatibility, and the potential for these new waveforms to be accepted as the next generation waveforms in future mobile radio communication systems. It further delves into the requirements of 5G, such as low out of band radiation, and the problems with existing systems. The lesson concludes with a look at the different waveforms under consideration for the next generation, including windowed OFDM, filtered OFDM, and filter bank multi carrier.
