• A New Frequency Planning for Improved Capacity and Coverage in Sectorized OFDMA Cellular Networks 

      Martín-Vega, Francisco J.; Gómez, Gerardo; Aguayo-Torres, Maria del Carmen (2015-09-02)
      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 

      Martín-Vega, Francisco J.; Gómez, Gerardo; Aguayo-Torres, Maria del Carmen (2015-09-02)
      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 ...
    • Modelado y Análisis de técnicas de acceso basadas en geolocalización para V2V 

      Alarcón, Daniel; Gómez, Gerardo; Martín-Vega, Francisco J. (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 

      Villena-Rodríguez, Alejandro; Martín-Vega, Francisco J.; Lopez-Martinez, F. Javier; Gómez, Gerardo; Outes-Carnero, José; [et al.] (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, Maria 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 

      Marín-Barranquero, José C.; Gómez, Gerardo; Martín-Vega, Francisco J. (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 ...
