Autoencoder-based Optimization of Multi-user Molecule Mixture Communication Systems
Bastian Heinlein, Nuria Zurita Jiménez, Kaikai Zhu +4
In this paper, we introduce an autoencoder (AE)-based scheme for end-to-end optimization of a multi-user molecule mixture communication system. In the proposed scheme, each transmi…
The Road to Next-Generation Multiple Access: A 50-Year Tutorial Review
Yuanwei Liu, Chongjun Ouyang, Zhiguo Ding +1
The evolution of wireless communications has been significantly influenced by remarkable advancements in multiple access (MA) technologies over the past five decades, shaping the l…
Performance Tradeoff Between Overhead and Achievable SNR in RIS Beam Training
Friedemann Laue, Vahid Jamali, Robert Schober
Efficient beam training is the key challenge in the codebook-based configuration of reconfigurable intelligent surfaces (RISs) because the beam training overhead can have a strong…
Reconfigurable Intelligent Surfaces for 6G: Emerging Hardware Architectures, Applications, and Open Challenges
Ertugrul Basar, George C. Alexandropoulos, Yuanwei Liu +5
Reconfigurable intelligent surfaces (RISs) are rapidly gaining prominence in the realm of fifth generation (5G)-Advanced, and predominantly, sixth generation (6G) mobile networks,…
TTD Configurations for Near-Field Beamforming: Parallel, Serial, or Hybrid?
Zhaolin Wang, Xidong Mu, Yuanwei Liu +1
True-time delayers (TTDs) are popular components for hybrid beamforming architectures to combat the spatial-wideband effect in wideband near-field communications. In this paper, a…
