On the Optimality of Rate Balancing for Max-Min Fair Multicasting
Sadaf Syed, Wolfgang Utschick, Michael Joham
The max-min fair (MMF) multicasting problem is known to be NP-hard. In this work, we analytically derive the optimal solution to this NP-hard problem and establish the equivalence…
Sum-Rate Optimisation of a Multi-User STAR-RIS-Aided System with Low Complexity
Sadaf Syed, Wolfgang Utschick, Michael Joham
Reconfigurable intelligent surface (RIS) is a promising technology for future wireless communication systems. However, the conventional RIS can only reflect the incident signal. He…
Sparse Bayesian Generative Modeling for Compressive Sensing
Benedikt Böck, Sadaf Syed, Wolfgang Utschick
This work addresses the fundamental linear inverse problem in compressive sensing (CS) by introducing a new type of regularizing generative prior. Our proposed method utilizes idea…
Bilinear Precoder Based Efficient Rate Splitting Method in FDD Systems
Sadaf Syed, Donia Ben Amor, Michael Joham +1
In this work, we propose a low-cost rate splitting (RS) technique for a multi-user multiple-input single-output (MISO) system operating in frequency division duplex (FDD) mode. The…
Low Complexity Rate Splitting Approach in RIS-Aided Systems Based on Channel Statistics
Sadaf Syed, Michael Joham, Wolfgang Utschick
Rate splitting multiple access (RSMA) and reconfigurable intelligent surface (RIS) are two prospective technologies for improving the spectral and energy efficiency in future wirel…
