Generalized Beyond-Diagonal RIS Architectures: Theory and Design via Structure-oriented Symmetric Unitary Projection
Xiaohua Zhou, Tianyu Fang, Yijie Mao +1
Beyond-diagonal reconfigurable intelligent surface (BD-RIS), which enables advanced wave control through interconnection of RIS elements, are gaining growing recognition as a promi…
Uplink Rate Splitting Multiple Access with Imperfect Channel State Information and Interference Cancellation
Farjam Karim, Nurul Huda Mahmood, Arthur S. de Sena +3
This article investigates the performance of uplink rate splitting multiple access (RSMA) in a two-user scenario, addressing an under-explored domain compared to its downlink count…
Meta-Learning Based Optimization for Large Scale Wireless Systems
Rafael Cerna Loli, Bruno Clerckx
Optimization algorithms for wireless systems play a fundamental role in improving their performance and efficiency. However, it is known that the complexity of conventional optimiz…
A Meta-Learning Based Precoder Optimization Framework for Rate-Splitting Multiple Access
Rafael Cerna Loli, Bruno Clerckx
In this letter, we propose the use of a meta-learning based precoder optimization framework to directly optimize the Rate-Splitting Multiple Access (RSMA) precoders with partial Ch…
Channel Estimation for Beyond Diagonal Reconfigurable Intelligent Surfaces with Group-Connected Architectures
Hongyu Li, Yumeng Zhang, Bruno Clerckx
We study channel estimation for a beyond diagonal reconfigurable intelligent surface (BD-RIS) aided multiple input single output system. We first describe the channel estimation st…
Rate-Splitting Multiple Access: The First Prototype and Experimental Validation of its Superiority over SDMA and NOMA
Xinze Lyu, Sundar Aditya, Junghoon Kim +1
In multi-user multi-antenna communications, it is well-known in theory that Rate-Splitting Multiple Access (RSMA) can achieve a higher spectral efficiency than both Space Division…
