A discrete bit loading algorithm for FBMC/OQAM
Caus López, Marius; Pérez Neira, Ana Isabel; García Armada, Ana (2012-06)
Article
Accés restringit per política de l'editorialIn this letter the discrete rate maximization problem is investigated for FBMC/OQAM. The analysis reveals that if there is crosstalk certain bit allocations violate the power constraints. Aiming at ensuring the feasibility ... -
Adaptive block Diagonalization and user scheduling with out of cluster interferenced
García Fernández, Juan José; García Armada, Ana; Rubio López, Javier; Pascual Iserte, Antonio; Font Bach, Oriol; Bartzoudis, Nikolaos (2014)
Text en actes de congrés
Accés restringit per política de l'editorialInterference in a cellular network is one of the main impairments that needs to be overcome. Coordination among the Base Stations may enable the use of the interference to improve the transmission rate at the cost of ... -
Asymptotic analysis of multiuser-MIMO networks with battery-constrained receivers
Rubio López, Javier; Pascual Iserte, Antonio; García Fernández, Juan José; García Armada, Ana; Font Bach, Oriol; Bartzoudis, Nikolaos (2014)
Text en actes de congrés
Accés restringit per política de l'editorialIn this paper, we present an asymptotic analysis of the behavior of a network where the mobile terminals are considered to be battery-powered devices provided with energy harvesting capabilities. The asymptotic analysis ... -
Design of pre-coding and combining in hybrid analog-digital massive MIMO with phase noise
Corvaja, Roberto; García Armada, Ana; Vazquez, Miguel Angel; Pérez Neira, Ana Isabel (Institute of Electrical and Electronics Engineers (IEEE), 2017)
Text en actes de congrés
Accés restringit per acord de confidencialitatThe design of massive MIMO, especially at millimeter waves, requires a trade-off between cost and power consumption, balancing the complexity and the performance in terms of achievable rate. A recent trend in the design ... -
Energy profiling of FPGA-based PHY-layer building blocks encountered in modern wireless communication systems
Bartzoudis, Nikolaos; Font Bach, Oriol; Payaró Llisterri, Miquel; Pascual Iserte, Antonio; Rubio López, Javier; García Fernández, Juan José; García Armada, Ana (2014)
Comunicació de congrés
Accés restringit per política de l'editorialCharacterizing the energy cost of different physical (PHY) layer building blocks is becoming increasingly important in modern cellular-based communications, considering the cross sector requirements for performance ... -
Mutual information analysis of frequency packing schemes in multi-beam satellite systemswith phase noise
Bas, Joan; Caus López, Marius; Pérez Neira, Ana Isabel; Modenini, Andrea; Ebert, Johannes; García Armada, Ana (Curran, 2017)
Text en actes de congrés
Accés restringit per política de l'editorialThis paper analyzes frequency packing schemes applied to multibeam satellite systems. In order to simulate a realistic scenario we have taken into account the presence of co-channel interference and spectrum limitations. ... -
Network-MIMO backhauling for QOS-constrained relay transmission
Vidal Manzano, José; Agustín de Dios, Adrián; Lagén Morancho, Sandra; Valera, Eduard; Muñoz Medina, Olga; García Armada, Ana; Sánchez Fernández, Matilde (2011)
Text en actes de congrés
Accés restringit per política de l'editorialA relay station (RS)-based cellular system deployment is considered, where multiple base stations (BS) cooperate in the BS-RS in-band transmission for the downlink. With the joint optimization of the resources allocated ... -
Performance of waterfilling-based schemes for interference cancellation in 4G networks
Pablo González, Mari Luz; García Armada, Ana; Sánchez Fernández, Matilde; Pascual Iserte, Antonio; Payaró Llisterri, Miquel (Institute of Electrical and Electronics Engineers (IEEE), 2012)
Text en actes de congrés
Accés restringit per política de l'editorialIn this work we consider the optimization of the power assigned to the user streams in a coordinated base station downlink environment with Orthogonal Frequency Division Modulation (OFDM). In this scenario the base stations ... -
Power and bandwidth allocation based on age of information metrics in satellite uplink channels
Torres Gómez, Jorge; Morales Céspedes, Maximo; Shaat, Musbah; Pérez Neira, Ana Isabel; García Armada, Ana (Institute of Electrical and Electronics Engineers (IEEE), 2022)
Text en actes de congrés
Accés obertCommunication links over satellites allow interconnecting very distant regions to provide service where the terrestrial networks are limited. In this scenario, it is of major importance to devise mechanisms accounting for ... -
Resource allocation in multi-antenna MAC networks: FBMC vs OFDM
Payaró Llisterri, Miquel; Pascual Iserte, Antonio; García Armada, Ana; Sánchez Fernández, Matilde (2011)
Text en actes de congrés
Accés restringit per política de l'editorialThis paper addresses the problem of resource allocation in a multiple access channel where several mobile terminals (MT’s) are transmitting simultaneously to a single receiving base station, all of them with multiple ... -
Scheduling and precoding in hybrid analog-digital multiantenna spectrum sharing systems
Vazquez, Miguel Angel; Pérez Neira, Ana Isabel; Corvaja, Roberto; García Armada, Ana; Lagunas Hernandez, Miguel A. (Institute of Electrical and Electronics Engineers (IEEE), 2017)
Text en actes de congrés
Accés restringit per política de l'editorialThis paper investigates scheduling and precoding techniques via hybrid analog-digital transmitters in mm-wave frequency bands. As in spectrum sharing sub-6GHz scenarios, the presence of non-intended receivers limits the ...
