Index Modulation Aided Phase-Rotated AFDM for Efficient Integrated Sensing and Communication: Framework, Optimization and Performance Analysis
Shiqi Cui, Zeping Sui, Tianqi Mao +7
Affine frequency division multiplexing (AFDM) has emerged as a competitive waveform for integrated sensing and communication (ISAC) in high-mobility scenarios, but its data-depende…
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…
Joint Chirp Parameter Selection and Low-Complexity MMSE Receiver Design for AFDM Systems
Ruiyuan Mao, Qu Luo, Jianguo Li +5
Affine frequency division multiplexing (AFDM) has emerged as a promising waveform against doubly selective channels under high-mobility communication scenarios. Optimal chirp param…
AFDM-Enabled Integrated Sensing and Communication: Theoretical Framework and Pilot Design
Fan Zhang, Zhaocheng Wang, Tianqi Mao +6
The integrated sensing and communication (ISAC) has been envisioned as one representative usage scenario of sixth-generation (6G) network. However, the unprecedented characteristic…
