Receive Diversity for Differential Binary Noise Modulation
Paulo V. B. Tomé, André A. dos Anjos, Hugerles S. Silva +3
Differential binary noise (DBN) modulation encodes information in the polarity transition of a reused noise realization, dispensing channel state information and carrier-phase reco…
On-Off Digital Noise Modulation with Fluid Antenna Systems over - Fading Channels
Daniel C. Araújo, André A. dos Anjos, Hugerles S. Silva +2
This letter proposes the integration of on-off digital noise (OODN) modulation with fluid antenna systems (FASs). A unified analytical framework is developed to evaluate the perfor…
On--Off Digital Noise Modulation under Multi-User Co-Channel Interference
Daniel C. Araújo, André A. dos Anjos, Hugerles S. Silva
This letter analyzes the performance of on-off digital noise (OODN) modulation under multi-user scenarios. While prior works have addressed single-link operation, the impact of co-…
Channel Estimation for Flexible Intelligent Metasurface Aided MIMO Communications
Vinícius L. Romano, André L. F. de Almeida, Daniel C. Araújo
Flexible Intelligent Metasurfaces (FIMs) enable wireless systems to adapt their three-dimensional geometry through morphing, thereby providing new spatial degrees of freedom. Howev…
Adaptive Modulation and Coding based on Reinforcement Learning for 5G Networks
Mateus P. Mota, Daniel C. Araujo, Francisco Hugo Costa Neto +2
We design a self-exploratory reinforcement learning (RL) framework, based on the Q-learning algorithm, that enables the base station (BS) to choose a suitable modulation and coding…
