Probabilistic Symbol-Level Precoding based Affine Frequency Division Multiplexing Transmission
Shuntian Tang, Xinyi Wang, Shuangyang Li +3
Affine frequency division multiplexing (AFDM) has recently gained significant attention due to its robustness against time-frequency doubly selective channel fading. However, the h…
Toward Low-Altitude Embodied Intelligence: A Sensing-Communication-Computation-Control Closed-Loop Perspective
Jihao Luo, Zesong Fei, Xinyi Wang +3
The rapid growth of the low-altitude economy drives increasingly autonomous unmanned aerial vehicle (UAV) operations, giving rise to low-altitude embodied intelligence (LAEI), in w…
Doppler-Resilient LEO Satellite OFDM Transmission with Affine Frequency Domain Pilot
Shuntian Tang, Xiaomei Wu, Xinyi Wang +5
Orthogonal frequency division multiplexing (OFDM) based low Earth orbit (LEO) satellite communication system suffers from severe Doppler shifts, while {the Doppler-resilient affine…
A Novel Symbol Level Precoding based AFDM Transmission Framework: Offloading Equalization Burden to Transmitter Side
Shuntian Tang, Zesong Fei, Xinyi Wang +3
Affine Frequency Division Multiplexing (AFDM) has attracted considerable attention for its robustness to Doppler effects. However, its high receiver-side computational complexity r…
Revealing the Trade-off in ISAC Systems: The KL Divergence Perspective
Zesong Fei, Shuntian Tang, Xinyi Wang +3
Integrated sensing and communication (ISAC) is regarded as a promising technique for 6G communication network. In this letter, we investigate the Pareto bound of the ISAC system in…
