Efficiency Meets Reliability: Enhanced Generalized Interleaved Transform for Random Multiplexing
Ming Wang, Shufeng Li, Lei Liu +2
To meet the demands of 6G wireless systems operating in high-mobility scenarios, this paper presents a design of a random multiplexing (RM) communication system that is both storag…
Differential Spatial Modulation with Transmit Diversity for Pinching-Antenna Systems
Yiwei Tao, Yao Ge, Dong Li +2
Pinching antenna (PA) systems provide a new spatial degree of freedom by flexible activation of pinching positions. However, the resulting effective channel strongly depends on the…
Flag-Preamble-Based Delay-Doppler Channel Estimation for Next-Evolution Waveforms
Yuan Liu, Yilin Qi, Caiqin Li +3
Accurate delay-Doppler channel estimation is critical for next-evolution waveforms (NEWs) to enable reliable signal detection. This paper proposes a robust channel estimation algor…
Optimizing Fluid Antenna Configurations for Constructive Interference Precoding
Wenxuan Sun, Mingjie Shao, Luteng Zhu +3
The fluid antenna system (FAS) has emerged as a new physical-layer concept to provide enhanced propagation conditions for multiuser multiple-input multiple-output (MIMO) communicat…
Affine Frequency Division Multiplexing with Index Modulation: Full Diversity Condition, Performance Analysis, and Low-Complexity Detection
Yiwei Tao, Miaowen Wen, Yao Ge +3
Affine frequency division multiplexing (AFDM) is a novel modulation technique based on chirp signals that has been recently proposed as an effective solution for highly reliable co…
