@unpublished{53282, abstract = {{Modern wireless communication systems are expected to provide improved latency and reliability. To meet these expectations, a short packet length is needed, which makes the first-order Shannon rate an inaccurate performance metric for such communication systems. A more accurate approximation of the achievable rates of finite-block-length (FBL) coding regimes is known as the normal approximation (NA). It is therefore of substantial interest to study the optimization of the FBL rate in multi-user multiple-input multiple-output (MIMO) systems, in which each user may transmit and/or receive multiple data streams. Hence, we formulate a general optimization problem for improving the spectral and energy efficiency of multi-user MIMO-aided ultra-reliable low-latency communication (URLLC) systems, which are assisted by reconfigurable intelligent surfaces (RISs). We show that a RIS is capable of substantially improving the performance of multi-user MIMO-aided URLLC systems. Moreover, the benefits of RIS increase as the packet length and/or the tolerable bit error rate are reduced. This reveals that RISs can be even more beneficial in URLLC systems for improving the FBL rates than in conventional systems approaching Shannon rates.}}, author = {{Soleymani, Mohammad and Santamaria, Ignacio and Jorswieck, Eduard and Schober, Robert and Hanzo, Lajos}}, booktitle = {{arXiv:2402.16434}}, title = {{{Optimization of the Downlink Spectral- and Energy-Efficiency of RIS-aided Multi-user URLLC MIMO Systems}}}, year = {{2024}}, } @inproceedings{53259, author = {{Soleymani, Mohammad and Santamaria, Ignacio and Sezgin, Aydin and Jorswieck, Eduard}}, booktitle = {{2023 IEEE 9th International Workshop on Computational Advances in Multi-Sensor Adaptive Processing (CAMSAP)}}, publisher = {{IEEE}}, title = {{{Maximization of Minimum Rate in MIMO OFDM RIS-Assisted Broadcast Channels}}}, doi = {{10.1109/camsap58249.2023.10403459}}, year = {{2024}}, } @inproceedings{53258, author = {{Soleymani, Mohammad and Santamaria, Ignacio and Jorswieck, Eduard}}, booktitle = {{GLOBECOM 2023 - 2023 IEEE Global Communications Conference}}, publisher = {{IEEE}}, title = {{{NOMA-Based Improper Signaling for MIMO STAR-RIS-Assisted Broadcast Channels with Hardware Impairments}}}, doi = {{10.1109/globecom54140.2023.10437458}}, year = {{2024}}, } @inproceedings{53304, author = {{Kuschel, Maurice and Hasija, Tanuj and Marrinan, Timothy}}, booktitle = {{ICASSP 2024 - 2024 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP)}}, publisher = {{IEEE}}, title = {{{Rademacher Complexity Regularization for Correlation-Based Multiview Representation Learning}}}, doi = {{10.1109/icassp48485.2024.10446173}}, year = {{2024}}, } @article{54668, abstract = {{Samples of dielectric optical waveguides of rib or strip type in thin-film lithium niobate (TFLN) technology are characterized with respect to their optical loss using the Fabry-Pérot method.
