Performance analysis of channelized cellular systems with dynamic channel allocation [PDF]

IEEE Transactions on Vehicular Technology, 2003
We present an analytical model to compute the blocking probability in channelized cellular systems with dynamic channel allocation. We model the channel occupancy in a cell by a two-dimensional (2D) Markov chain, which can be solved to obtain the blocking probability in each cell. We apply our analytical model to linear highway systems with and without

Two-Dimensional Dynamic Logic Resource Allocation for Scalable RIS Channel Emulation [PDF]

Sensors
This paper addresses the critical scalability challenge in Hardware-in-the-Loop (HIL) channel emulation for massive RIS-assisted 6G environments. We propose a Two-Dimensional Dynamic Logic Resource Allocation (2D-DLRA) architecture that decouples ...

Dynamic Bandwidth Allocation for NG-PONs With Channel Bonding [PDF]

IEEE Communications Letters, 2022
La unión de canales es una técnica propuesta recientemente para proporcionar velocidades de línea agregadas más altas en las NG-PON al permitir que las ONU operen simultáneamente en múltiples longitudes de onda. Por otro lado, el algoritmo de Asignación Dinámica de Ancho de Banda (dba) asigna a cada ONU el intervalo de tiempo de concesión en cada trama

Channel swapping based dynamic channel allocation [PDF]

ICUPC '98. IEEE 1998 International Conference on Universal Personal Communications. Conference Proceedings (Cat. No.98TH8384), 2002
Several DCA schemes have been proposed to improve the quality and carried traffic in mobile cellular radio system. Most of these schemes assign channels to calls based on the constraint imposed by cochannel interference, and ignore the ACI (adjacent channel interference) constraint.
