    • A Hybrid VLC-RF Portable Phasor Measurement Unit for Deep Tunnels 
      Soto, Ismael; Nilson Rodrigues, Rafael; Massuyama, Gabriel; Seguel, Fabián; Palacios Játiva, Pablo; Azurdia Meza, César; Krommenacker, Nicolás (MDPI, 2020)
      In this manuscript we propose a hybrid Visible Light Communication and Radio Frequency (VLC-RF) scheme for the implementation of a portable Phaser Measurement Unit (PMU) for deep underground tunnels. Through computer ...
    • A novel frequency domain visible light communication (VLC) three-dimensional trilateration system for ... 
      Firoozabadi, Ali Dehghan; Azurdia Meza, César; Soto, Ismael; Seguel, Fabian; Krommenacker, Nicolas; Iturralde, Daniel; Charpentier, Patrick; Zabala-Blanco, David (MDPI AG, 2019)
    • A VLC Channel Model for Underground Mining Environments With Scattering and Shadowing 
      Palacios Jativa, Pablo; Azurdia Meza, César; Sánchez, Iván; Seguel, Fabián; Zabala Blanco, David; Firoozabadi, Ali Dehghan; Gutiérrez, Carlos A.; Soto, Ismael (IEEE-Inst Electrical Electronics Engineers, 2020)
      Underground mining is an industry that preserves the miners' safety and efficiency in their work using wireless communication systems as a tool. In addition to communication links characterized by radio frequency signals, ...
    • Bit error probability of VLC systems in underground mining channels with imperfect CSI 
      Palacios Jativa, Pablo Geovanny; Azurdia Meza, Cesar Augusto; Zabala Blanco, David; Gutiérrez, Carlos A.; Sánchez, Iván; Castillo Soria, Francisco R.; Seguel, Fabián (Elsevier, 2022)
      Analytical expressions of the statistical distribution of the underground mining visible light communication (UMVLC) square-channel gain are derived considering scattering, shadowing, and a random position and orientation ...
    • Interference mitigation for visible light communications in underground mines using angle diversity receivers 
      Palacios Játiva, Pablo Geovanny; Román Canizares, Milton; Azurdia Meza, César; Zabala Blanco, David; Dehghan Firoozabad, Ali; Seguel, Fabián; Montejo Sánchez, Samuel; Soto, Ismael (MDPI, 2020)
      This paper proposes two solutions based on angle diversity receivers (ADRs) to mitigate inter-cell interference (ICI) in underground mining visible light communication (VLC) systems, one of them is a novel approach. A ...
