Multi-Satellite MIMO Systems for Direct User-Satellite Communications: A Survey
Zohre Mashayekh Bakhsh, Yasaman Omid, Gaojie Chen +3
Advancements in satellite technology have made direct-to-device connectivity a viable solution for ensuring global access. This method is designed to provide internet connectivity…
Sherman-Morrison Regularization for ELAA Iterative Linear Precoding
Jinfei Wang, Yi Ma, Na Yi +1
The design of iterative linear precoding is recently challenged by extremely large aperture array (ELAA) systems, where conventional preconditioning techniques could hardly improve…
Constellation-Oriented Perturbation for Scalable-Complexity MIMO Nonlinear Precoding
Jinfei Wang, Yi Ma, Na Yi +2
In this paper, a novel nonlinear precoding (NLP) technique, namely constellation-oriented perturbation (COP), is proposed to tackle the scalability problem inherent in conventional…
Power Allocation for FDMA-URLLC Downlink with Random Channel Assignment
Jinfei Wang, Yi Ma, Na Yi +1
Concerning ultra-reliable low-latency communication (URLLC) for the downlink operating in the frequency-division multiple-access with random channel assignment, a lightweight power…
