报告摘要：

This talk will introduce affine frequency division multiplexing (AFDM) modulation, which is one of the most promising backwards-compatible waveforms for highly resilient and scalable 6G+ systems. Specifically, AFDM subsumes the legacy OFDM as a special case and can be efficiently implemented through minimal modification of the OFDM transmitter. By modulating different data symbols over multiple orthogonal chirp subcarriers, AFDM is able to attain the full channel diversity and hence significantly improved error rate performance compared to OFDM. Besides the basic principles, I will introduce a series of recent advances on AFDM including 1)Non-orthogonal AFDM; 2)Generalized spatial modulation aided AFDM (GSM-AFDM); 3)AFDM aided sparse code multiple access (AFDM-SCMA); and 4)MIMO-AFDM in the Face of Hardware Impairments. A real-time lab-environment USRP proof-of-concept implementation of AFDM (against OFDM), developed by the 6G Lab of Essex, will also be shown.
