OTFS a Novel Modulation Scheme Addressing the Challenges of 5G
In this talk I will introduce a novel modulation scheme referred to as OTFS (Orthogonal Time Frequency and Space) which is based on multiplexing information QAM symbols on localized pulses in the delay-Doppler signal representation. I will explain the mathematical foundations of OTFS, emphasizing how the underlying structure establishes a conceptual link between communication and Radar theory. I will show how OTFS naturally generalizes conventional time and frequency modulations such as TDM and FDM. I will also discuss the unique way OTFS waveforms couple with the wireless channel which allows the coherent combining of all the time and frequency diversity modes of the channel to maximize the received energy. Finally, I will explain the intrinsic advantages of OTFS over multicarrier modulation schemes in the context of various 5G use cases such as MU-MIMO equalization and precoding, communication under high Doppler conditions (V2X and V2V) and communication under strict power constraints (such as in IoT).

I never comment on videos... great presenter and great content. More questions now but definitely good step to start finding answers. Thank you Ronny

[@adnantariq1516]

This an excellent talk for freshers in this research domain. Lots of doubts are clear now. Thank you, Prof. Would it have been very helpful if your content could be shared?

great

Amazing video and very well explained. Can you recommend any other literature that I could read since this video is now 4 years old I've been in the wireless industry for almost 20 years now and this looks extremely promising. One question I have is are there handsets out there today that can (de)modulate OFTS?

How can we get the cc?

He just taught complete signal processing & communicaton in 1.5 hour.

This man was my intro to real analysis professor. One of the best teachers I've ever had.

[@sakshamaghoslya]

@@aidanokeeffe7928 Then you must be going places.
