      Master thesis (pre-Bologna period)
      Open Access
      [ANGLÈS] Based on the definition of the access network planning architecture and the voice and data traffic evolution forecast, this document derives engineering rules for network dimensioning in rural areas. Network ...

      Based on the definition of the access network architecture and the forecast of voice and data traffic evolution, this paper derives engineering rules for radio network dimensioning of 3G femtocell-based access networks in ...

    • Dynamic base station switch on/off strategies for sustainable wireless networks 

      Rubio López, Javier; Pascual Iserte, Antonio; Olmo Alòs, Jaume del; Vidal Manzano, José (2014)
      Conference lecture
      Restricted access - publisher's policy
      In this paper, we present a procedure for switching on and off base stations (BSs) that are powered with solar panels and have finite batteries. In the scenario under consideration it is considered that the BSs are placed ...

    • Network dimensioning and base station on/off switching strategies for sustainable deployments in remote areas 

      Rubio López, Javier; Olmo Alòs, Jaume del; Pascual Iserte, Antonio; Vidal Manzano, José; Muñoz Medina, Olga; Agustín de Dios, Adrián (2017-12)
      Article
      Open Access
      This paper provides a methodology for the dimensioning of the access network in remote rural areas, considering the progressive introduction of cellular services in these regions. A 3G small cell (SC) network with one or ...

    • Polar coding for common message only wiretap broadcast channel 

      Olmo Alòs, Jaume del; Rodríguez Fonollosa, Javier (Institute of Electrical and Electronics Engineers (IEEE), 2019)
      Conference lecture
      Restricted access - publisher's policy
      A polar coding scheme is proposed for the Wiretap Broadcast Channel with two legitimate receivers and one eavesdropper. We consider a model in which the transmitter wishes to send a private and a confidential message that ...

    • Polar coding for confidential broadcasting 

      Olmo Alòs, Jaume del; Rodríguez Fonollosa, Javier (2020-01-27)
      Article
      Open Access
      A polar coding scheme is proposed for the Wiretap Broadcast Channel with two legitimate receivers and one eavesdropper. We consider a model in which the transmitter wishes to send the same private (non-confidential) message ...

    • Polar coding for the wiretap broadcast channel 

      Olmo Alòs, Jaume del (Universitat Politècnica de Catalunya, 2019-10-22)
      Doctoral thesis
      Open Access
      In the next era of communications, where heterogeneous, asynchronous and ultra-low latency networks are drawn on the horizon, classical cryptography might be inadequate due to the excessive cost of maintaining a public-key ...

    • Polar coding for the wiretap broadcast channel with multiple messages 

      Olmo Alòs, Jaume del; Rodríguez Fonollosa, Javier (Institute of Electrical and Electronics Engineers (IEEE), 2020)
      Conference lecture
      Open Access
      A polar coding scheme is proposed for the Wiretap Broadcast Channel with two legitimate receivers and one eaves-dropper. We consider a model in which the transmitter wishes to to reliably send different confidential and ...

    • Strong secrecy on a class of degraded broadcast channels using polar codes 

      Olmo Alòs, Jaume del; Rodríguez Fonollosa, Javier (2016)
      Conference lecture
      Open Access
      Two polar coding schemes are proposed for the degraded broadcast channel under different reliability and secrecy requirements. In these settings, the transmitter wishes to send multiple messages to a set of legitimate ...

    • Strong secrecy on a class of degraded broadcast channels using polar codes 

      Olmo Alòs, Jaume del; Rodríguez Fonollosa, Javier (2018-06-15)
      Article
      Open Access
      Asymptotic secrecy-capacity achieving polar coding schemes are proposed for the memoryless degraded broadcast channel under different reliability and secrecy requirements: layered decoding or layered secrecy. In these ...

    • User association for load balancing in heterogeneous networks powered with energy harvesting sources 

      Rubio López, Javier; Pascual Iserte, Antonio; Olmo Alòs, Jaume del; Vidal Manzano, José (2014)
      Conference report
      Restricted access - publisher's policy
      User association strategies for heterogeneous networks are proposed in order to balance the load among different base stations (BSs) and obtain higher downlink aggregate network utility based on per-user throughputs. ...

    • User association strategies in HetNets leading to rate balancing under energy constraints 

      Rubio López, Javier; Pascual Iserte, Antonio; Olmo Alòs, Jaume del; Vidal Manzano, José (2017-12)
      Article
      Open Access
      This paper deals with the development of several strategies for associating users to base stations (BSs) in heterogeneous networks. These strategies are able to balance the rate among users and BSs and increase the overall ...
