Talk Title: Affine Frequency Division Multiplexing (AFDM): Principle, implementation, and challenges
Sixth-generation (6G) are expected to introduce new usage scenarios, along with enhanced and new capabilities. In 6G networks, high-mobility communications that enjoy high reliability and operate at high carrier frequencies will play a critical role. However, orthogonal frequency division multiplexing, widely used in current wireless networks, suffers from significant performance degradation in high-mobility scenarios, since frequency dispersion resulting from Doppler shifts destroys the subcarrier orthogonality and causes inter-carrier interference. Recently, affine frequency division multiplexing (AFDM) has emerged as a promising waveform, which can achieve the optimal diversity order over doubly dispersive channels.
After revisiting the characteristics of doubly dispersive channels, this talk introduces the fundamentals of AFDM, and then some implementation issues of AFDM with our proposed solutions. Finally, some open challenges of AFDM are discussed.
