A New Frequency Planning for Improved Capacity and Coverage in Sectorized OFDMA Cellular Networks
One of the main challenges in cellular systems is how to reduce Other Cells Interference (OCI) while keeping high spectral efficiency and high coverage probability. Since the beginning of cellular technologies, frequency ... -
A New Tractable Model to Estimate the Uplink Inter-Cell Interference in LTE
This paper presents a tractable model to estimate the uplink Inter-Cell Interference (ICI) in fully loaded LTE networks. Interfering users are considered to be uniformly distributed in an annulus so that evaluation of the ... -
Arquitectura HW para decodificador Two-Step SOVA con recorridos hacia atrás sistólicos
In this paper, a novel SOVA (Soft-Output Viterbi algorithm) decoder using systolic arrays to carry out the trace-back method is presented. Systolic arrays are associated with high data rates and small resource requirements, ... -
Coordinated Multicast/Unicast Transmission on 5G: A Novel Approach for Linear Broadcasting
Jiménez-Soria, David; Martín-Vega, Francisco J.; Aguayo-Torres, María del Carmen
(Springer, 2021-09-16)
Linear broadcasting services, with a scheduled programming, constitute a paramount tel-ecommunication service for today’s society. Although the existing technology is mature, current linear broadcast ... -
Modelado y Análisis de técnicas de acceso basadas en geolocalización para V2V
(2021-09-20)In this work, two geolocation-based access (GLOC) techniques for vehicular communications are presented and analyzed. These techniques, named Single-Lane Partition (SLP) and Multiple-Lane Partition (MLP) differ on the ... -
On the system performance of DFT-S-OFDM and CP-OFDM for 5G Uplink in mmWave band
(2021-09-20)Both conventional Cyclic Prefix Orthogonal Frequency Division Multiplexing (CP-OFDM) and Discrete Fourier Transform Spread OFDM (DFT-S-OFDM) have been adopted for their use in the Physical Uplink Shared Channel (PUSCH) in ... -
Prestaciones de LTE sobre el canal aeronáutico
Martín-Vega, Francisco J.; Gómez, Gerardo; Mosquera, Carlos; Aguayo-Torres, María del Carmen (2014-09-03)
This work assesses the performance of Long Term Evolution (LTE) downlink over aeronautical channels associated to arrival, parking and en-route scenarios. The huge velocity related to some of these scenarios poses the ... -
Reutilización Fraccional de Frecuencia con Sectorización sobre Redes Celulares
(2017-09-06)In this paper, we investigate the downlink of homogeneous LTE cellular networks with Fractional Frequency Reuse (FFR) and sectorized antennas where non-ideal radiation patterns have been considered. Three frequency allocation ... -
Selección Dinámica de Celda en los Enlaces Ascendente y Descendente de Redes Heterogéneas: Estudio de las Estratégias Acoplada y Desacoplada
Dynamic cell selection (DCS) and decoupled access are two disruptive candidate schemes for cell association in future 5G networks. DCS provides adaptation to fast channel variations, which results in potential performance ... -
Understanding the impact of line-of-sight in the ergodic spectral efficiency of cellular networks
Garcia-Corrales, Celia; Martín-Vega, Francisco J.; Lopez-Martinez, F. Javier; Cañete-Corripio, Francisco Javier; Paris-Angel, Jose Francisco (2018-09-27)
In this paper we investigate the impact of lineof-sight (LoS) condition in the ergodic spectral efficiency of cellular networks. To achieve this goal, we have considered the kappa-mu shadowed model, which is a general model ...
