A Novel Low-Complexity Dual-Domain Expectation Propagation Detection Aided AFDM for Future Communications
Qin Yi, Ping Yang, Zilong Liu +3
This paper presents a dual-domain low-complexity expectation propagation (EP) detection framework for affine frequency division multiplexing (AFDM) systems. By analyzing the struct…
OTFS-based Integrated Positioning and Communication Systems with Low-Resolution ADCs
Yueyi Yang, Zeping Sui, Zilong Liu +1
This paper proposes a two-phase orthogonal time frequency space (OTFS)-based integrated positioning and communication (IPAC) framework under realistic low-resolution analog-to-digi…
On the Robustness of AFDM and OTFS Against Passive Eavesdroppers
Vincent Savaux, Hyeon Seok Rou, Zeping Sui +2
We investigate the robustness of affine frequency division multiplexing (AFDM) and orthogonal time frequency space (OTFS) waveforms against passive eavesdroppers performing brute-f…
Optimal Real-time Communication in 6G Ultra-Massive V2X Mobile Networks
He Huang, Zilong Liu, Zeping Sui +4
This paper introduces a novel cooperative vehicular communication algorithm tailored for future 6G ultra-massive vehicle-to-everything (V2X) networks leveraging integrated space-ai…
Error Rate Analysis and Low-Complexity Receiver Design for Zero-Padded AFDM
Qin Yi, Zeping Sui, Zilong Liu
This paper studies the error rate performance and low-complexity receiver design for zero-padded affine frequency division multiplexing (ZP-AFDM) systems. By exploiting the unique…
Energy Detection over Composite Shadowed Fading Channels with Inverse Gaussian Distribution in Ultra mMTC Networks
He Huang, Zeping Sui, Zilong Liu +4
This paper investigates the characteristics of energy detection (ED) over composite - shadowed fading channels in ultra machine-type communication (mMTC) networks. We have de…
