The Seven Worlds and Experiences of the Wireless Metaverse: Challenges and Opportunities

no code implementations20 Apr 2023 Omar Hashash, Christina Chaccour, Walid Saad, Tao Yu, Kei Sakaguchi, Merouane Debbah

We then articulate how these experiences bring forth interactions between diverse metaverse constituents, namely, a) humans and avatars and b) connected intelligence systems and their digital twins (DTs).

Disentangling Learnable and Memorizable Data via Contrastive Learning for Semantic Communications

no code implementations18 Dec 2022 Christina Chaccour, Walid Saad

Deep semantic clusters of highest confidence are considered learnable, semantic-rich data, i. e., data that can be used to build a language in a semantic communications system.

Less Data, More Knowledge: Building Next Generation Semantic Communication Networks

no code implementations25 Nov 2022 Christina Chaccour, Walid Saad, Merouane Debbah, Zhu Han, H. Vincent Poor

In this tutorial, we present the first rigorous vision of a scalable end-to-end semantic communication network that is founded on novel concepts from artificial intelligence (AI), causal reasoning, and communication theory.

Seven Defining Features of Terahertz (THz) Wireless Systems: A Fellowship of Communication and Sensing

no code implementations15 Feb 2021 Christina Chaccour, Mehdi Naderi Soorki, Walid Saad, Mehdi Bennis, Petar Popovski, Merouane Debbah

Based on these fundamentals, we characterize seven unique defining features of THz wireless systems: 1) Quasi-opticality of the band, 2) THz-tailored wireless architectures, 3) Synergy with lower frequency bands, 4) Joint sensing and communication systems, 5) PHY-layer procedures, 6) Spectrum access techniques, and 7) Real-time network optimization.
