  • Autonomous design for the MISO interference channel 

    Pérez Neira, Ana Isabel; Lagunas Hernandez, Miguel A.; Vázquez, Miguel Ángel (2011)
    Conference report
    Restricted access - publisher's policy
    This paper investigates the power control and beamforming design in the MISO-IC (Multiple Input Single Output-Interference Channel) when constraints are placed at the receivers’ input power. In this way regulatory ...
  • Confidential communication in downlink beamforming 

    Vázquez, Miguel Ángel; Pérez Neira, Ana Isabel; Lagunas Hernandez, Miguel A. (2012)
    Conference report
    Restricted access - publisher's policy
    This paper deals with the problem of secure transmission in downlinkbeamforming. In this scenario, a base station, which usually serves information to an amount of users, wants to transmit a confidential message to one ...
  • Joint temporal-spatial reference beamforming: EIG beamforming 

    Lagunas Hernandez, Miguel A.; Pérez Neira, Ana Isabel; Vázquez, Miguel Ángel (2010)
    Conference report
    Open Access
    Traditional methods for beamforming can be grouped in two families, the time reference beamformer and the spatial reference beamforming. Nevertheless, the increasing demand on receivers for location systems and high bandwidth ...
  • Open spectrum communication systems and optimized downlink beamforming 

    Vázquez, Miguel Ángel; Pérez Neira, Ana Isabel; Lagunas Hernandez, Miguel A. (2012)
    Conference report
    Restricted access - publisher's policy
    This paper addresses the problem of transmit beamforming in open spectrum communication systems. In these scenarios, the operator or the data communication provider delivers a set of base stations to the final users ...
  • Regulation and research on wireless communications 

    Lagunas Hernandez, Miguel A.; Pérez Neira, Ana Isabel; Vázquez, Miguel Ángel (2011)
    Conference report
    Restricted access - publisher's policy
    This paper describes wh ich are the major changes would occur in regulation policies and role of the regulation bodies due to the advance of technology development, research and innovation in telecommunications. The ...
  • Space-time ML receiver and its reciprocal transmitter design for interference networks 

    Vázquez, Miguel Ángel; Pérez Neira, Ana Isabel; Lagunas Hernandez, Miguel A. (2011)
    Conference report
    Restricted access - publisher's policy
    This paper examines a type of linear beamforming for communications in interference networks. First, a receiver beamformer design is derived from a Maximum Likelihood (ML) framework with Automatic Gain Control (AGC) ...
  • The challenge of the multiantenna-IC and practical solutions for the MISO case 

    Pérez Neira, Ana Isabel; Vázquez, Miguel Ángel; Lagunas Hernandez, Miguel A. (2010)
    Lecture
    Open Access
    The interference channel (IC) models a network of simultaneous communication node pairs. Interference is not a fundamental limitation: IA (interference alignment) is cooperative and not selfish. It avoids MUD. What about ...
  • Transmit beamforming for the MISO Interference Channel with asymmetric link gains 

    Vázquez, Miguel Ángel; Pérez Neira, Ana Isabel; Lagunas Hernandez, Miguel A. (2012)
    Conference report
    Restricted access - publisher's policy
    This paper proposes a transmit beamforming technique to cope with the problem of the Multiple Input Single Out- put Interference Channel (MISO IC). In this scenario, the achievable sum-rate is highly conditioned by the ...
