Integrated sensing and communications in the 3GPP New Radio: sensing limits
Santiago Fernández, Javier Giménez, Mari Carmen Aguayo-Torres +1
Integrated Sensing and Communications (ISAC) is regarded as a key element of the beyond-fifth-generation (5G) and sixth-generation (6G) systems, raising the question of whether cur…
User Selection in Near-Field Gigantic MIMO Systems with Modular Arrays
José P. González-Coma, Santiago Fernández, F. Javier López-Martínez
Modular Arrays (MAs) are a promising architecture to enable multi-user communications in next-generation multiple-input multiple-output (MIMO) systems based on extra-large (XL) or…
How Should One Fit Channel Measurements to Fading Distributions for Performance Analysis?
Santiago Fernández, José David Vega-Sánchez, Juan E. Galeote-Cazorla +1
Accurate channel modeling plays a pivotal role in optimizing communication systems, and fitting field measurements to stochastic models is crucial for capturing the key propagation…
Analytical Characterization of the Operational Diversity Order in Fading Channels
Santiago Fernández, J. Alfonso Bailón-Martínez, Juan E. Galeote-Cazorla +1
We introduce and characterize the operational diversity order (ODO) in fading channels, as a proxy to the classical notion of diversity order at any arbitrary operational signal-to…
