CFO-Robust Detection for 5G PRACH under Fading Channels: Analytical Modeling and Performance Evaluation
Daniel Alarcón-MartÃn, Mari Carmen Aguayo-Torres, Francisco J. MartÃn-Vega +1
The Physical Random Access Channel (PRACH) is essential for initial access and synchronization in both 5G and future 6G networks; however, its detection is highly sensitive to impa…
Deep Learning-Based CSI Prediction Framework for Channel Aging Mitigation in TDD 5G Systems
Francisco DÃaz-Ruiz, Francisco J. MartÃn-Vega, José Antonio Cortés +2
Time division duplexing (TDD) has become the dominant duplexing mode in 5G and beyond due to its ability to exploit channel reciprocity for efficient downlink channel state informa…
Optimizing MIMO Efficiency in 5G through Precoding Matrix Techniques
Francisco DÃaz-Ruiz, Francisco J. MartÃn-Vega, Gerardo Gómez +1
Multiple-Input Multiple-Output (MIMO) systems play a crucial role in fifth-generation (5G) mobile communications, primarily achieved through the utilization of precoding matrix tec…
