Low-complexity Frequency Domain Equalization for filtered-AFDM over General Physical Channels
Cheng Shen, Chenyang Zhang, Jinhong Yuan
Affine frequency division multiplexing (AFDM) has emerged as a promising waveform for high-mobility communications. However, its equalization remains a practical challenge under ge…
Doppler Shift Keying Modulation for Uplink Multiple Access over Doubly-Dispersive Channels
Xuehan Wang, Jintao Wang, Hai Lin +4
The delay-Doppler (DD) domain modulation has been regarded as one of the most competitive candidates to support wireless communications for emerging high-mobility applications in t…
A Novel One-tap Equalizer for Zero-Padded AFDM System over Doubly Selective Channels
Chenyang Zhang, Akram Shafie, Cheng Shen +2
Recently, affine frequency division multiplexing (AFDM) has gained traction as a robust solution for doubly selective channels. In this paper, we present a novel low-complexity one…
