Matched Filtering-Based Channel Estimation for AFDM Systems in Doubly Selective Channels
Xiangjun Li, Zilong Liu, Zhengchun Zhou +1
Affine frequency division multiplexing (AFDM) has recently emerged as an excellent backward-compatible 6G waveform. In this paper, we study matched filtering (MF) assisted channel…

Grid Evolution for Doubly Fractional Channel Estimation in OTFS Systems
Xiangjun Li, Pingzhi Fan, Qianli Wang +1
In orthogonal time-frequency space communications, the performances of existing on-grid and off-grid channel estimation (CE) schemes are determined by the delay-Doppler (DD) grid d…
